The APS1006 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-lon (Li+) battery. The APS1006 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 APS1006 can also run at 100% duty cycle fo low dropout operation, extending battery life in

portable system. Pulse Skipping Mode operation at light loads provides very low output ripple voltage for noise sensitive applications.

The APS1006 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.
