DESCRIPTION

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

start-up and internally fixed soft-start time. When the

device is disabled, the output capacitor is discharged

through internal resistor.

Auto-Skip, Eco-mode™ for High Efficiency at

Light Loads

Switching Frequency: 900-kHz

UVLO, UVP, OTP and OVP Power Good Output

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

The TPS51312 is available in a 3 mm x 3 mm, 10-pin

DRC package (Green RoHS compliant and Pb free)

and is specified between –40°C and 85°C.
