The IR3638SPbF controller IC is designed to provide a simple synchronous Buck regulator for on-board DC to DC applications in a 14-pin SOIC. The IR3638 is designed specifically for tracking applications by providing the track input.

The IR3638SPbF operates at a fixed internal 400kHz switching frequency allowing the use of small external components.

The IR3638SPbF features a programmable soft start set by an external capacitor, under-voltage lockout and output under-voltage detection that latches off the device when an output short is detected.
