EUP3409
Dual 1.
5MHz, 800mA Synchronous Step-Down Converter
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.
