Product Summary
The IR3637STRPBF controller IC is designed to provide a simple synchronous Buck regulator for on-board DC to DC applicationsn in a small 8-pin SOIC. The output voltage can be precisely regulated using the internal 0.8V reference voltage for low voltage applications. The IR3637STRPBF operates at a fixed internal 400kHz switching frequency to reduce the component size. The device features under-voltage lockout for both input supplies, an external programmable soft-start function as well as output under-voltage detection that latches off the device when an output short is detected.
