AP2002
Description
The AP2002 is synchronous, fixed frequency, step-up DC/DC converters with true cutoff output, delivering high efficiency in a SOT23-6L package. Capable of supplying 3.6V at 180m A from 1.5V input, the device contains an internal NMOS switch and PMOS synchronous rectifier. A switching frequency of 1.2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The AP2002 can enter power saving mode at light loads.
The AP2002 has true cutoff function, when EN pin input logic low level, the device can disconnect output from input pletely, realizing the low shutdown current of under 0.1μA typical from VIN pin.
The device is available in the small profile SOT23-6L package.
