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.
