Typical application diagram Description The IR3840W SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC synchronous Buck regulator. The MOSFETs co- packaged with the on-chip PWM controller make IR3840W a space-efficient solution, providing accurate power delivery for low output voltage applications. IR3840W 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.
