ONOUS DESCRIPTION FEATURES The A7566 is synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6- lead SOT package. Capable of supplying 3.3V at 100mA from a single AA cell input, the device contain 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 current mode PWM design is internally compensated, reducing external parts count. The A7566 features continuous switching at light loads. The device features low shutdown current of und
