LN2240 600mA, 1.3MHz Micropower Synchronous Boost Converter ■ General Description 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 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 LN2240 features automatic shifting to power saving PFM Mode operation at light loads.
