Description

The IR3888A/B is an easy-to-use, fully integrated dc - dc Buck regulator. The onboard PWM controller and

OptiMOS? FETs with integrated bootstrap diode make IR3888A/B a small footprint solution, providing high

efficiency power delivery. Furthermore, it uses a fast Constant On-Time (COT) control scheme, which simplifies

design efforts and achieves fast control response.

The IR3888A/B has an internal low dropout voltage regulator, allowing operation with a single supply. It can also

operate with an external bias supply, extending the operating input voltage (PVin) range.

It features important protection functions, such as pre-bias start-up, thermally compensated current limits, over

voltage and under voltage protection, and thermal shutdown to give required system level security in the event of

fault conditions.
