Description

The IR3889 is an easy-to-use, fully integrated dc - dc Buck regulator. The onboard PWM controller and OptiMOS™

FETs with integrated bootstrap diode make IR3889 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 response.

The IR3889 has an internal low dropout voltage regulator, allowing operations with a single supply. It can also

operate with an external bias supply, with an extended operating input voltage (PVin) range from 2.0 V to 17 V.

The IR3889 is a versatile regulator, offering programmable switching frequency from 600 kHz to 2 MHz, four

selectable current limits, four selectable soft-start time, Forced Continuous Conduction Mode (FCCM) and Diode

Emulation Mode (DEM) operation.

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

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

event of fault conditions.
