Product Description

The IR3837MTRPBF is a SupIRBuck® easy-to-use fully-integrated and highly efficient DC/DC synchronous Buck Regulator for use with data center applications. The onboard PWM controller and MOSFETs make IR3837 a space-efficient solution, providing accurate power delivery for low output voltage applications. IR3837 is a versatile regulator which offers programmability of switching frequency and current limit while operates 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 and thermal shutdown to give required system level security in the event of fault conditions. IR3837 offers margining capability through Vref pin. During the margining operation, PGood tracks Vref via feedback to ensure correct status of the output voltage. The internal LDO enables the device to operate from a single supply.
