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.
