introduction
introduction
the fp6397 is a high efficiency, high frequency synchronous dc-dc step-down converter. 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 fp6397 fault protection includes over current protection, short circuit protection, uvlo and thermal shutdown. the internal soft-start function prevents inrush current at turn-on.
the fp6397 is offered in sot-23-5 and sot-23-6 packages.
