Typical Applications
TPS54360DDAR is suitable for 6 applications: 24V Industrial Bus Power Supply, Automotive Infotainment and Body Electronics, Telecom and Networking Equipment, Point-of-Load Converters for Motor Drive and MCU Rails, LED Lighting and Constant-Voltage Fixtures, Battery-Powered and Test Instrumentation.
24V Industrial Bus Power Supply
The TPS54360DDAR's 4.5V to 60V input range directly addresses 24V industrial rails that experience surges and transients well above nominal. With 3.5A output capability and current-mode control, it regulates typical 5V, 12V, or 15V PLC and sensor-supply rails with fast transient response. Its 65V absolute maximum adds margin against inductive load spikes, and Eco-mode keeps light-load efficiency high for always-on factory equipment.
Recommended
Automotive Infotainment and Body Electronics
For 12V automotive systems, the TPS54360DDAR tolerates crank and transient conditions with its 60V input rating. The precision enable pin supports programmable UVLO and power sequencing for CAN transceivers and audio amplifiers. For formally qualified designs, the pin-compatible TPS54360QDDARQ1 AEC-Q100 variant drops onto the same footprint. Adjustable 100kHz-2.5MHz frequency allows compliance-driven EMI tuning.
Recommended
Telecom and Networking Equipment
Telecom infrastructure converts -48V-adjacent or high intermediate bus voltages down to board rails; the TPS54360DDAR's 60V input covers 24V and 48V-class intermediate buses with margin. Its 3.5A output feeds line cards, Ethernet PHYs, and microcontroller rails, while adjustable frequency up to 2.5MHz allows small magnetics in space-constrained switch ports. Eco-mode maintains efficiency during low-traffic standby periods.
Recommended
Point-of-Load Converters for Motor Drive and MCU Rails
The TPS54360DDAR serves as a local point-of-load buck feeding motor-drive controllers and microcontrollers from 24V rails. Its 4.5A minimum peak current limit rides through motor inrush, and current-mode control delivers clean transient response for MCU clock stability. Pairing with a DRV-class gate driver front end, the converter supplies logic and gate-drive bias rails with 0.8V reference accuracy across -40C to +125C.
Recommended
LED Lighting and Constant-Voltage Fixtures
Industrial and architectural LED fixtures driven from wide-range AC-DC front ends benefit from the TPS54360DDAR's 60V input tolerance and 0.8V-to-58.8V output span, allowing direct LED-string supply rails. High adjustable switching frequency shrinks inductor size for compact driver modules, while thermal shutdown protects enclosed fixtures. Eco-mode reduces standby losses in dimmed or occupancy-controlled luminaires.
Recommended
Battery-Powered and Test Instrumentation
Portable test equipment powered by 12V to 48V battery packs uses the TPS54360DDAR to generate stable analog and digital rails. The 92mOhm integrated high-side MOSFET maximizes efficiency to extend battery runtime, and Eco-mode pulse skipping preserves light-load efficiency during idle measurement phases. The precision enable supports software-controlled power-up sequencing of ADC front ends and displays.

Key Differentiators
- 60V input tolerance in SOIC-class package (vs TPS5450DDAR)
- Cost-efficient 3.5A rating (vs TPS54560DDAR)
- Eco-mode light-load efficiency (vs LM5164DDAR)
Design Notes
The HSOIC-8 DDA PowerPAD is the primary heat-dissipation path. Solder the pad to a PCB copper area of at least 1 square inch with a 4x4 array of 0.3mm thermal vias to the ground plane. At 24V input, 5V output, and 3.5A load, dissipation approaches several watts; without proper PowerPAD attachment the junction will hit thermal shutdown near 170C typical.
Keep the PH-to-inductor loop and input capacitor loop as small as possible to minimize radiated EMI. Place the BOOT capacitor (0.1uF) directly between BOOT and PH pins. Route the VSENSE feedback trace away from the PH node and inductor to avoid switching-noise coupling into the feedback divider; use ground guard traces if necessary.
Do not exceed the 65V absolute maximum at VIN - add input TVS for 24V bus surge environments. The RT/CLK resistor must always be populated for freewheeling operation; a floating pin disables the converter. Set EN divider for the required UVLO so the converter does not start during brownout dips at high input voltage.
