EUP3426
3A, Synchronous Step-Down Converter
DESCRIPTION
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 diode.
The EUP3426 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...
