EUP3426 - Eutech Microelectronics

EUP3426 Synchronous Step-Down Converter

The EUP3426 is a 1 MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 3A output current. The EUP3426 operates from an input range of 2.7V to 5.5V and provides a regulated output voltage from 0.6V to 5V. The internal synchronous power switch improves efficiency and eliminates the need for an external Schottky d.

Features

short circuit and thermal protection circuits to improve system reliability. Internally soft-start avoids input inrush current during startup. The EUP3426 is available in TDFN 3mm × 3mm 10-pin package with the exposed pad and SOP-8 package with the exposed pad.
