Synchronous Boost DC/DC Regulator

General Description

The LP6206 is high efficiency synchronous, fixed

frequency, current-mode step-up converter with

output to input disconnect. A PWM step-up DC/DC

converters optimized to provide a high efficiency

solution to medium power system.

When LP6206

is disabled, the internal conduction path from the

battery. This output disconnect feature reduces the

shutdown current to typically only 50nA.

the

devices regulates the output voltage up to 6V from

either a 2cell NiMH/NiCd or a single-cell Li-ion

Battery with a 500KHz fixed frequency switching.

These features minimize overall solution footprint

by allowing the use of tiny, low profile inductors

and ceramic capacitors.
