3 Description
The TPS62851x is a family of pin-to-pin 0.5-A, 1-A,
2-A (continuous), and 3-A (peak) high efficiency, easyto-
use, synchronous step-down DC/DC converters.
They are based on a peak current mode control
topology. Low resistive switches allow up to 2-A
continuous output current and 3-A peak current. The
switching frequency is internally fixed at 2.25 MHz
and can also be synchronized to an external clock
in the range from 1.8 MHz to 4 MHz. In PWM/PFM
mode, the TPS62851x automatically enters power
save mode at light loads to maintain high efficiency
across the whole load range. The TPS62851x provide
a 1 output voltage accuracy in PWM mode, which
helps design a power supply with high output voltage
accuracy. The SS/TR pin allows setting the start-up
time or tracking the output voltage to an external
source, which allows external sequencing of different
supply rails and limits the inrush current during startup.
The TPS62851x is available in an 8-pin 1.60-mm
× 2.10-mm SOT583 package, offering a high power
density solution.
