EUP3421 - Synchronous Step-Down Converter

General Description

The EUP3421 is a 1 MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 2A output current.

The EUP3421 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 improve system reliability. Externally adjustable soft-start avoids input inrush current during startup. The EUP3421 is available in SOP-8 package.

EUP3421 2A, Synchronous Step-Down Converter DESCRIPTION The EUP3421 is a 1 MHz fixed frequency synchronous, current-mode, step-down dc-dc converter capable of providing up to 2A output current. The EUP3421 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 diode. Forced PWM operation provides very low output ripple voltage for noise sensitive applications. The EUP3421 features short circuit and thermal protection circuits to improve system reliability. Externally adjustable soft-start avoids input inrush current during startup. The EUP3421 is available in SOP-8 package. FEATURES 2.7V to 5.
