TPS57160QDGQRQ1 Overview
A buck converter, or step-down regulator, is a switching power-conversion IC that efficiently reduces a higher input voltage to a lower regulated output by switching an internal or external transistor at high frequency and filtering the result with an inductor and capacitors. Within the power management hierarchy, it sits under DC-DC converters, a subset of voltage regulators, and complements LDOs where conversion efficiency matters more than ultra-low noise.
Key features include a wide 3.5 V to 60 V input range with AEC-Q100 automotive qualification, current-mode control that simplifies external compensation, and TI Eco-Mode pulse-skip operation that cuts no-load input supply current to 116 uA. Shutdown supply current via the enable pin is only 1.5 uA, critical for always-connected automotive modules that must minimize quiescent battery drain.
Architecturally, the integrated low-drain-to-source on-resistance high-side MOSFET and its gate-drive circuitry inside the package allow high efficiency while keeping junction temperature low at high output currents. Internally fixed undervoltage lockout is set at 2.5 V and is adjustable via the enable pin for tighter input supervision. A RT/CLK pin supports resistor-programmed switching frequency as well as synchronization to an external clock, easing EMI planning in multi-converter systems.
Typical applications include automotive 12 V and 48 V battery-rail point-of-load supplies, industrial 24 V bus step-down power, and telecom or avionics wide-input auxiliary rails feeding microcontrollers, CAN transceivers, and sensors. The 60 V rating provides ample surge headroom on load-dump-prone automotive inputs.
When designing with this part, keep the PowerPAD soldered to a substantial copper ground plane for thermal performance, and verify compensation network values against the switching frequency chosen. Non-synchronous topology means a proper external catch diode must be selected for peak currents.

Typical Applications
TPS57160QDGQRQ1 is suitable for 6 applications: Automotive 12V Battery Rail Power, Industrial 24V Bus Step-Down, 48V Telecom and PoE Auxiliary Supplies, Battery-Powered Portable Instruments, LED Lighting Drivers and Signage, Motor Control and Actuator Logic Supplies.
Automotive 12V Battery Rail Power
The TPS57160QDGQRQ1 fits automotive 12 V battery-rail point-of-load supplies because its 60 V input rating provides load-dump and transient headroom well beyond the 40 V jump-start window common in vehicle front-end designs. Its AEC-Q100 qualification and -40C to +125C operating range satisfy OEM environmental requirements for body control modules, gateways, and lighting ECUs. Placed directly after a reverse-polarity protection stage, the converter steps the battery rail down to 5 V or 3.3 V microcontroller and transceiver supplies at up to 1.5 A. Eco-Mode operation cuts no-load input current to 116 uA and shutdown current to 1.5 uA, preserving battery charge during key-off periods where modules remain partially powered for CAN wake-up monitoring.

Industrial 24V Bus Step-Down
Industrial 24 V control panels and PLC I/O modules benefit from the TPS57160QDGQRQ1's wide 3.5 V to 60 V input, which absorbs surge events on factory power distribution without a pre-regulator. The 1.5 A output directly powers microcontrollers, fieldbus transceivers, and analog front ends from a single conversion stage, improving efficiency versus two-stage architectures. Current-mode control allows simple external compensation and flexible component selection, which shortens design cycles for variant boards with different output voltages set only by the VSENSE divider (0.8 V to 58 V adjustable). The integrated 200-mohm high-side MOSFET delivers high efficiency at full load, reducing enclosure thermal load in sealed DIN-rail housings, and the RT/CLK pin permits synchronization across multiple converters to control EMI.
Recommended
48V Telecom and PoE Auxiliary Supplies
Telecom -48 V rectified rails and 48 V PoE intermediate buses fall comfortably within the TPS57160QDGQRQ1's 60 V maximum input, allowing a single integrated-FET buck to generate housekeeping 5 V or 3.3 V supplies for hot-swap controllers, microcontrollers, and status circuitry. The non-synchronous topology requires only an external catch diode, keeping the solution compact in the 10-pin MSOP-PowerPAD (DGQ) footprint. Eco-Mode pulse-skip control maintains high light-load efficiency and low output ripple during standby, while 1.5 uA shutdown current eases compliance with telecom energy-efficiency targets. Adjustable undervoltage lockout via the enable pin lets designers gate converter start precisely against the input rail, sequencing the logic supply after input supervision and surge-protection stages settle.
Recommended
Battery-Powered Portable Instruments
Battery-powered test equipment and portable instrumentation gain long standby life from the TPS57160QDGQRQ1's 116 uA Eco-Mode no-load current and 1.5 uA shutdown current. The wide input range accepts multi-cell battery stacks - from 4-series Li-ion (about 12 V to 17 V) up to higher-voltage stacks - without front-end pre-regulation, and the 1.5 A output covers displays, wireless modules, and sensor bias rails. Current-mode control gives fast transient response when radios or displays switch load states, simplifying external compensation across temperature. Because the output is adjustable to 58 V, the same converter can also bias piezo drivers or avalanche photodiode stages in measurement front ends, consolidating multiple discrete regulators into one proven automotive-qualified silicon platform.
Recommended
LED Lighting Drivers and Signage
Wide-input LED luminaires, signage, and emergency-exit lighting derive their constant-voltage feed from the TPS57160QDGQRQ1 by regulating an LED string supply up to 58 V, close to the converter's output ceiling, which suits longer series strings. The 60 V input tolerance covers rectified 24 V AC industrial lighting supplies and automotive headlamp buses with transient margin. Current-mode control maintains stable operation across the varying effective impedance of LED loads, and the adjustable UVLO lets the converter latch off below a defined battery threshold to protect deep-cycle batteries from over-discharge. The DGQ PowerPAD package dissipates conversion losses efficiently in enclosed fixtures, and Eco-Mode keeps idle drain low in occupancy-sensor-gated fixtures that spend most time at light load.
Recommended
Motor Control and Actuator Logic Supplies
Motor-drive boards and industrial actuators use the TPS57160QDGQRQ1 to generate clean logic supplies (5 V or 3.3 V) from the same 24 V to 48 V bus that powers the motor stage, sharing protection circuitry and reducing BOM count. Its 60 V input covers regenerative bus-pump events when motors decelerate into capacitive loads. The 1.5 A capacity powers gate-driver housekeeping, position-sensor interfaces, and microcontrollers simultaneously. The RT/CLK synchronization pin lets the logic-supply converter track the motor inverter's switching frequency, avoiding beat-frequency audible noise and control-loop interaction. Current-mode control rejects input ripple caused by inverter switching, and the automotive AEC-Q100 grade extends usage into electric-vehicle auxiliary actuators such as pumps, flaps, and throttle-position mechanisms.

- 5x higher output current than the economy variant (vs TPS54060MDGQTEP)
Design Notes
Solder the exposed PowerPAD of the DGQ package to a continuous ground copper pour with thermal vias (array of 6-8 vias on 1.0 mm pitch). Estimated: at VIN = 24 V, VOUT = 5 V, IOUT = 1.5 A, and 90% efficiency, device loss is roughly 0.8 W; without proper PowerPAD attachment the die temperature will exceed safe limits even though the board-level ambient is moderate. Verify junction temperature against your PCB stackup using the theta-JA data in the TI datasheet thermal information table.
Keep the PH node loop (VIN, PH, catch diode, PWR_GND) as short and compact as possible to minimize the high-di/dt switching area and reduce radiated EMI. Place the bootstrap capacitor between BOOT and PH within 2-3 mm of the pins. Route the VSENSE feedback trace away from the PH node and inductor to avoid injecting switching noise into the error amplifier; use a ground-referenced sense trace to the output capacitor.
Because the TPS57160-Q1 is non-synchronous, the external catch diode must be a Schottky rated above the maximum input voltage (60 V application needs at least a 60-100 V diode) and above the peak switch current, placed directly at the PH pin. Do not omit the RT/CLK resistor - leaving the pin floating is an invalid condition. When using adjustable UVLO through EN, size the divider so hysteresis prevents chattering on slowly rising automotive supply ramps.
Use the RT/CLK synchronization input to lock multiple converters on the board to one frequency or apply intentional frequency dithering to reduce peak EMI emissions in automotive CISPR-oriented designs. Slow the switch edge indirectly through careful layout rather than adding series resistance at PH. Snubber components across the catch diode can damp ringing if conducted/radiated measurements show resonance near 20-50 MHz.
