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.
