Datasheet
LP6202
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.
