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.
