INTEGRATED 12A SYNCHRONOUS BUCK REGULATOR

The IR3840 SupIRBuckTM is an easy-to-use, fully ntegrated and highly efficient DC/DC synchronous Buck Regulator The MOSFETs co- packaged with the on-chip PWM Controller make R3840 a space-efficient solution, providing accurate power delivery for low output voltage applications. R3840 is a versatile Regulator which offers programmability of start up time, switching requency 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. t also features important protection functions, such as Pre-Bias startup, hiccup current limit and hermal shutdown to give required system level security in the event of fault conditions.
