LN2240 Datasheet (natlinear) - 1.3MHz Micropower Synchronous Boost Converter

LN2240, 1.3MHz Micropower Synchronous Boost Converter

The LN2240 is a synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6-lead ThinSOT package.

Capable of supplying 5V at 600mA from a Lithium Battery input, the devices contain an internal NMOS switch and PMOS synchronous rectifier.

A switching frequency of 1.3MHz mi

LN2240 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. Both devices are available in the low profile (1mm) SOT-23 package.
