產品說明
the fp6335 is a high efficiency, high frequency synchronous dc-dc step-down pulse width modulated (pwm) 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 fp6335 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 fp6335 is offered in sot-23-5, sot-23-6 and tdfn-6 (2mm×2mm) packages.
