IR3841WMTR1PBF Datasheet PDF - Infineon

The IR3841WMTR1PBF is a SupIRBuck® easy-to-use fully-integrated and highly efficient DC/DC synchronous Buck Regulator for use with Netcom applications. IR3841W is a versatile regulator which offers programmability of start-up time, switching frequency and current limit while operating in wide input and output voltage range. The switching frequency is programmable from 250kHz to 1.5MHz for an optimum solution. It also features important protection functions, such as pre-bias startup, hiccup current limit and thermal shutdown to give required system level security in the event of fault conditions.
