產品說明
the fp6395 is a high efficiency, high frequency synchronous dc-dc step-down led driver. 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 fp6395 fault protection includes over current protection, short circuit protection, uvlo, input over voltage protection and thermal shutdown.
the fp6395 is offered in tdfn-6 (1.6mm×1.6mm) tdfn-6 (2mm×2mm) and sot-23-5 packages.
