描述 Description

The IR3823A is an easy-to-use, fully integrated dc - dc Buck regulator. The onboard PWM controller and MOSFETs

with integrated bootstrap diode make IR3823A 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

provides fast control response.

The IR3823A has an internal low dropout voltage regulator, allowing operation with a single supply. The IR3823A

is a versatile regulator, offering programmable switching frequency from 600 kHz to 2 MHz, two selectable soft

start times, 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.
