TPS628510 - Step-Down Converters

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.
