Description
The IR3825 SupIRBuck® is an easy-to-use, fully
integrated and highly efficient DC/DC regulator.
The onboard PWM controller and MOSFETs make
IR3825 a space-efficient solution, providing
accurate power delivery.
IR3825 is a versatile regulator, operating with wide
input and output voltage range, which offers
programmable switching frequency from 300kHz to
1.5MHz, and three selectable current limits.
It features important protection functions, such as
Pre-Bias startup, thermally compensated current
limit, over voltage protection and thermal shutdown
to give required system level security in the event of
fault conditions.
