DC-DC CONVERTER BOOST (STEP-UP) 800mA, 1.3MHz MICROPOWER SYNCHRONOUS
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. The current mode PWM design is internally pensated, reducing external parts count. The A7508 Features automatic shifting to power saving PFM Mode operation at light loads....
