Preliminary Datasheet
LP6206
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.
