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
- Vp for tracking applications and sequencing
- Vref is available externally to enable margining
- External synchronization with Smooth Clocking
- Enhanced pre-bias startup
- Body braking to improve transient
- Integrated MOSFET drivers and bootstrap diode
- Thermal shut down
- Programmable power good output with tracking
- 0.5% Accurate reference voltage
