DESCRIPTION

The EUP3409 contains two independent 1.5MHz

constant frequency, current mode, PWM step-down

converters. Each converter integrates a main switch and

a synchronous rectifier for high efficiency without an

external Schottky diode. The EUP3409 is ideal for

powering portable equipment that runs from a single

cell Lithium-Ion (Li+) battery. Each converter can

supply 800mA of load current from a 2.5V to 5.5V

input voltage. The output voltage can be regulated as

low as 0.6V. The EUP3409 can also run at 100% duty

cycle for low dropout applications.
