High Frequency Synchronous PWM Controller For Tracking Applications. The IR3638SPBF Controller IC Is Designed To Provide A Simple Synchronous Buck Regulator For On-board DC To DC Applications In A Small 14-pin SOIC.

The IR3638 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 IR3638 operates at a fixed internal 400kHz switching frequency allowing the use of small external components. The device 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.
