Typical Applications
TPS62130RGTR is suitable for 6 applications: Standard 12V Rail Supplies, Point-of-Load (POL) from Li-ion Batteries, Solid-State Drives (SSD), Embedded Systems, LDO Replacement, Mobile PCs, Tablets, Modems, Cameras.
Standard 12V Rail Supplies
The TPS62130RGTR efficiently steps down 12V rails to lower voltages (e.g., 5V, 3.3V) for powering digital loads. Its 3A output current and high efficiency (up to 95%) minimize power loss and heat generation. The wide input range (3-17V) provides ample headroom for 12V systems with transients. The DCS-Control topology ensures fast transient response, maintaining stable output voltage during load steps. This makes it ideal for industrial control, networking equipment, and test instrumentation where reliable power delivery is critical.

Point-of-Load (POL) from Li-ion Batteries
The TPS62130RGTR is well-suited for POL converters powered by single or multiple Li-ion batteries. Its input range of 3V to 17V covers 1-4 cell battery configurations. The low quiescent current (17Β΅A) in power-save mode extends battery life during standby. The 2.5MHz switching frequency allows the use of small inductors, reducing PCB area. This makes it ideal for portable devices, drones, and handheld instruments where efficiency and size are critical.
Recommended
Solid-State Drives (SSD)
The TPS62130RGTR provides a compact, efficient power solution for SSDs. It can step down 5V or 12V rails to the core voltages (e.g., 3.3V, 1.8V) required by NAND flash and controllers. The 3A output current supports the peak power demands of SSD write operations. The small 3x3mm QFN package saves board space, which is crucial in M.2 and 2.5-inch SSD form factors. The power-good output enables proper sequencing of multiple rails.
Recommended
Embedded Systems
The TPS62130RGTR is ideal for powering embedded systems, including microcontrollers, FPGAs, and peripherals. Its adjustable output (0.9V to 6V) can generate multiple voltage rails from a single input. The enable pin allows for power sequencing, and the soft-start feature reduces inrush current. The high efficiency reduces thermal stress, enabling operation in enclosed environments. This makes it suitable for IoT devices, industrial controllers, and automotive infotainment systems.
Recommended
LDO Replacement
The TPS62130RGTR can replace linear regulators (LDOs) in applications where efficiency is a priority. For example, converting 12V to 3.3V at 3A, an LDO would dissipate over 26W, while the TPS62130RGTR dissipates only a few watts. This reduces heat and eliminates the need for large heatsinks. However, the switching regulator introduces output ripple and noise, so additional filtering may be required for noise-sensitive loads. It is an excellent choice for powering digital circuits where efficiency and thermal performance are critical.
Recommended
Mobile PCs, Tablets, Modems, Cameras
The TPS62130RGTR is well-suited for battery-powered consumer electronics. Its low quiescent current (17Β΅A) and high efficiency extend battery life. The small package and high switching frequency minimize solution size, fitting into slim devices. The wide input range accommodates various battery configurations. The power-good and enable pins facilitate power management. This makes it ideal for mobile PCs, tablets, modems, and cameras where space and power efficiency are paramount.

Key Differentiators
- High output current of 3A in a small 3x3mm package (vs TPS62140RGTR)
- DCS-Control topology for fast transient response (vs TPS62150RGTR)
- Wide input voltage range (3V to 17V) (vs TLV62130RGTR)
Design Notes
For optimal performance, place the input capacitor (10Β΅F) and output capacitor (22Β΅F) as close as possible to the VIN and VOUT pins. Use a solid ground plane and connect the exposed pad to the ground plane with multiple vias to enhance thermal dissipation. Keep the switch node (SW) trace short and wide to minimize parasitic inductance and EMI.
The TPS62130RGTR can dissipate significant power at high input-output voltage differences. For example, at 12V input, 3.3V output, and 3A load, power dissipation is approximately 26W. The 3x3mm QFN package has a thermal resistance of about 40Β°C/W (theta_JA) with proper PCB layout. Ensure adequate copper area and thermal vias to keep the junction temperature below 125Β°C.
Do not exceed the absolute maximum input voltage of 17V. Use a 10Β΅F input capacitor with low ESR to handle input transients. The soft-start capacitor should be selected to limit inrush current; a typical value is 10nF for a 1ms startup time. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy.
