The IR3853 SupIRBuck TM 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
IR3853 a space-efficient solution, providing
accurate power delivery for low output voltage
applications.
IR3853 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,
over-voltage, and thermal shutdown to give
required system level security in the event of fault
conditions.
