A7508 - 1.3MHz MICROPOWER SYNCHRONOUS DC-DC CONVERTER BOOST

Datasheet Summary

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.

Features

  • automatic shifting to power saving PFM Mode operation at light loads. Antiringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode, and the devices feature low shutdown current of under 1μA. The A7508 is available in SOT-26 Package.

AiT Semiconductor Inc. www.ait-ic.com A7508 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 compensated, reducing external parts count. The A7508 features automatic shifting to power saving PFM Mode operation at light loads.
