The IR3853MTRPBF is a SupIRBuck? easy-to-use fully-integrated and highly efficient DC/DC synchronous Buck Regulator for us e with embedded telecom systems. IR3853 is a versatile regulator which offers programmability of startup 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, overvoltage and thermal shutdown to give required system level security in the event of fault conditions.
