FP6378A
High Efficiency 1MH/az852AT
Synchronous Step Down Regulator
Description
The FP6378A is a high efficiency, high frequency
synchronous DC-DC step-down regulator. The
100% duty cycle feature provides low dropout
operation, extending battery life in portable systems.
The internal synchronous switch increases efficiency
and eliminates the need for external Schottky diode.
At shutdown mode, the input supply current is less
than 1µA.
The current limit protection and on-chip thermal
shutdown features provide protection against any
combination of overload or ambient temperature.
