3 Description
The TPS62850x is a family of pin-to-pin 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 externally adjustable from 1.8
MHz to 4 MHz and can also be synchronized to
an external clock in the same frequency range. In
PWM and PFM mode, the TPS62850x automatically
enters power save mode at light loads to maintain
high efficiency across the whole load range. The
TPS62850x provides a 1 output voltage accuracy
in PWM mode, which helps design a power supply
with high output voltage accuracy, fulfilling tight supply
voltage requirements of digital processors and FPGA.
The TPS62850x is available in an 8-pin 1.60-mm ×
2.10-mm SOT583 package.
