TPS51312 datasheet



Partnumber : TPS51312DRCR, Device Marking : S51312

The TPS51312 is a high-efficiency, synchronous, step-down DC/DC converter. It supports 3-A (maximum) of dc output current at output voltages from 0.6 V to 3.3 V.

The D-CAP2 mode adaptive on time control allows a small footprint when designed using all ceramic output capacitors and offers a low external component count. The device also features auto-skip function at light load condition, pre-biased  tart-up and internally fixed soft-start time. When the device is disabled, the output capacitor is discharged through internal resistor.


1. Fixed Voltage Servo Soft-Start Function

2. Auto-Skip, Eco-mode for High Efficiency at Light Loads

3. Switching Frequency: 900-kHz

4. UVLO, UVP, OTP and OVP Power Good Output

5. Cycle-By-Cycle Current Limit, Latch-off OCP
