Typical Applications
TPS62130RGTR is suitable for 6 applications: 12V Rail Point-of-Load Supply, Li-ion Battery-Powered Portable Devices, Solid-State Drives and Storage, Embedded Systems and MCU Power, Networking and Communication Equipment, LDO Replacement for High-Efficiency Rails.
12V Rail Point-of-Load Supply
The TPS62130RGTR accepts up to 17V input, so it converts a standard industrial 12V bus directly to low-voltage rails such as 3.3V, 2.5V, or 1.8V at up to 3A. Its DCS-Control topology provides fast transient response for load steps from processors and FPGAs, while the 2.5MHz switching frequency keeps the inductor below 5uH for a compact solution. Placed at the point of load, it eliminates distribution losses and improves regulation compared to a remote bulk supply.
Recommended
Li-ion Battery-Powered Portable Devices
With a 3V minimum input, the TPS62130RGTR operates from single or multiple Li-ion cells down to end-of-discharge voltage, delivering 0.9V-6V at 3A. In power-save mode it draws only about 17uA quiescent current, extending standby battery life in portable instruments and handhelds. The seamless PWM/power-save transition of DCS-Control avoids mode-change output glitches, keeping ADC and radio rails clean as load current changes between active and idle states.
Recommended
Solid-State Drives and Storage
SSDs require compact, efficient conversion from a 12V or 5V supply to controller and NAND core rails. The TPS62130RGTR's 3x3 mm VQFN-16 with exposed pad fits dense storage PCBs, and its 2.5MHz operation allows small magnetics with low profile. Overcurrent and overtemperature protection protect against fault conditions on the storage rail, while the Power Good output enables system-level monitoring of the controller supply during boot and sleep transitions.
Recommended
Embedded Systems and MCU Power
Embedded controllers need sequenced, well-regulated core and I/O rails. The TPS62130RGTR's SS/TR pin sets a controlled output ramp or tracks another rail, while the EN pin and open-drain Power Good output implement power-up sequencing between the 3A main rail and downstream low-current rails. The -40C to +85C operating range covers industrial enclosures, and the wide 3V-17V input tolerates unregulated or long-cable supply variations common in factory installations.
Recommended
Networking and Communication Equipment
Routers, switches, and line cards convert a 12V mid-plane supply into multiple POL rails. The TPS62130RGTR's 72 dB-class regulation performance and DCS-Control fast loop handle the bursty load profile of packet-processing silicon, while the high 2.5MHz frequency moves switching noise above sensitive receive bands, easing EMI filter design. Its efficiency across light load keeps idle-power figures low for energy-efficient network equipment designs.
Recommended
LDO Replacement for High-Efficiency Rails
Replacing a linear regulator with the TPS62130RGTR cuts dissipation dramatically: a 12V-to-3.3V 1A LDO wastes about 8.7W, while this synchronous buck achieves high efficiency and dissipates only a fraction of that in the 3x3 mm package. The exposed pad soldered to a copper pour handles the remaining losses without a heatsink. Soft-start control limits inrush during replacement retrofit, and the adjustable 0.9V-6V output matches most common LDO set points.

Key Differentiators
- Highest current in pin-compatible family (vs TPS62140RGTR)
- 17uA power-save quiescent current (vs TLV62130RGTR)
- Full feature set with SS/TR tracking (vs TPS62150RGTR)
Design Notes
Place the input capacitor within 2-3 mm of the PVIN/AVIN pins and the output capacitor close to VOS and the inductor to minimize parasitic inductance, which causes voltage spikes on the SW node at 2.5MHz switching. Solder the exposed thermal pad to a grounded copper pour with an array of thermal vias; the pad is the primary heat path and also the main ground connection for the power stage.
Keep the SW node copper area small to reduce radiated EMI, but wide enough for the 3A peak currents. Route the VOS feedback trace away from the SW node and inductor to avoid switching-noise coupling into the feedback loop. Star-ground the AGND pin to the exposed pad ground to keep control-circuit ground free of power-stage ripple.
Use the SS/TR pin capacitor to set a controlled startup ramp; omitting soft-start causes large inrush into the output capacitors and may trigger current limit. When using tracking or sequencing, follow the TI datasheet SS/TR ratio requirements. Do not exceed 17V input including transients, and verify inductor saturation current exceeds the 3A rating plus margin.
Compliance Information
RoHS compliant per TI product page. AEC-Q100 not applicable to standard TPS62130; automotive variant TPS62130A-Q1/TPS62150A-Q1 family exists for Q1 applications.
