The IR3837 SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC regulator.
The onboard PWM controller and MOSFETs make IR3837 a space-efficient solution, providing accurate power delivery for low output voltageapplications. IR3837 is a versatile regulator which offers programmability of switching frequency and current limit while operates in wide input andoutput 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 levelsecurity 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 statusof the output voltage.
The internal LDO enables the device to operate from a single supply. This internal LDO can be bypassed when an external bias voltage isavailable.
