LP6202A Datasheet, PDF (1/6 Pages) Lowpower Semiconductor inc – Synchronous Boost DC/DC Regulator

Preliminary Datasheet
LP6202A
Synchronous Boost DC/DC Regulator
General Description
The LP6202A 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.
