1 / 7 page  Preliminary Datasheet LP6202 LP6202 – Ver. 1.0 Datasheet Dec.-2007 Page 1 of 7 Synchronous Boost DC/DC Regulator General Description The LP6202 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficiency solution to medium power system. the devices work under the input voltage between 0.9V and 4.4V with a 1.4 MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
