The AP6015 is the first device in a family of low-noise current

mode synchronous step-down DC-DC converters.

It is ideally

suited for systems powered by either a 1-cell Li-ion battery or a 2-

to 3-cell NiCd/ NiMH/ Alkaline battery.

The AP6015 is a synchronous PWM converter with integrated

N- and P-channel power MOSFET switches.

Compared to the

asynchronous topology, synchronous rectification offers the

benefits of higher efficiency and reduced component count.

The

high operating frequency of 1MHz allows small inductor and

capacitor to be used.

This results in small pcb area.

During

shut-down, the standby current drops to 1

μA or less.

The

AP6015 is available in the 10-pin MSOP package.

It operates

over a free-air temperature range of -40
