ME3406
DESCRIPTION
The ME3406 is a 1.5Mhz constant frequency, slope pensated current mode PWM step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. The ME3406 can supply 600m A of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The ME3406 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Idle mode operation at light loads provides very low output ripple voltage for noise sensitive applications.
The ME3406 is offered in a low profile (1mm) 5-pin, SOT package, and is available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V.
