Description
The EP3001 is a 1.5MHz, constant frequency, slope compensated 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 EP3001 can supply 600mA of load current from a 2.5V to 5.5V input voltage.
The output voltage can be regulated as low as 0.6V.
The EP3001 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 EP3001is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an
adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V.
