Product Description

The IR3846MTRPBF is a SupIRBuck® easy-to-use fully-integrated and highly efficient DC/DC synchronous Buck Regulator for use with server applications. The onboard PWM controller and MOSFETs make IR3846 a space-efficient solution, providing accurate power delivery for low output voltage and high current applications. IR3846 is a versatile regulator which offers programmability of switching frequency and current limit while operating in wide input and output voltage range. The switching frequency is programmable from 300kHz to 1.5MHz for an optimum solution. It also features important protection functions, such as overvoltage protection (OVP), pre-bias startup, hiccup current limit and thermal shutdown to give required system level security in the event of fault conditions.
Enhanced line/load regulation with feed-forward
Internal digital soft-start
Enable input with voltage monitoring capability
Remote sense amplifier with true differential voltage sensing
Thermally compensated current limit and hiccup mode overcurrent protection
Smart LDO to enhance efficiency
