DESCRIPTION
The IR3892 SupIRBuck® is an easy-to-use, fully
integrated and highly efficient DC/DC regulator. The
onboard PWM controller and MOSFETs make IR3892
a space-efficient solution, providing accurate power
delivery for low output voltage.
IR3892 is a versatile regulator which offers
programmability of switching frequency and a fixed
current limit while operating in wide input and output
voltage range.
The switching frequency is programmable from
300kHz to 1.0MHz for an optimum solution.
It also features important protection functions, such as
Over Voltage Protection (OVP), Pre-Bias startup,
hiccup current limit and thermal shutdown to give
required system level security in the event of fault
conditions.
