EUP3425 - Synchronous Step-Down Converter

General Description

The EUP3425 is a 1MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 5A output current.

The EUP3425 operates from an input range of 2.7V to 5.5V and provides a regulated output voltage from 0.8V to 5V.

Key Features

  • short circuit and thermal protection circuits to increase system reliability. Externally adjustable soft-start SS pin allows for proper power on sequencing with respect to other power supllies and avoids input inrush current during startup. The EUP3425 is available in a low profile 14pin 3mm × 4mm TDFN package.

EUP3425 5A, 1MHz Synchronous Step-Down Converter DESCRIPTION The EUP3425 is a 1MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 5A output current. The EUP3425 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 increases efficiency and eliminates the need for an external Schottky diode. The EUP3425 can be externally set for either forced PWM continuous mode or pulse skipping mode. Forced PWM operation provides very low output ripple voltage for noise sensitive applications while pulse skipping operation improves light load efficiency by reducing switching loss.
