A7508 Description
The A7508 is a synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6-lead SOT package. Capable of supplying 5V at 800mA from a Lithium Battery input, the devices contain an internal NMOS switch and PMOS synchronous rectifier. A switching frequency of 1.3MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
