EUP3423 - Eutech Microelectronics

EUP3423 Synchronous Step-Down Converter

The EUP3423 is a 1 MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 3.2A output current. The EUP3423 operates from an input range of 2.7V to 5.5V and provides a regulated output voltage from 0.8V to 5V. The internal synchronous power switch improves efficiency and eliminates the need for an external Schottky.

Features

short circuit and thermal protection circuits to improve system reliability. Externally adjustable soft-start avoids input inrush current during startup. The EUP3423 is available in SOP-8 (EP) package.
