IR3887 - Infineon

IR3887 30A single-voltage synchronous Buck regulator

The IR3887 is an easy-to-use, fully integrated dc - dc Buck regulator. The onboard PWM controller and OptiMOS™ FETs with integrated bootstrap diode make IR3887 a small footprint solution, providing high-efficient power delivery. Furthermore, it uses a fast Constant On-Time (COT) control scheme, which simplifies the design efforts and achieves fast control re.
