Overview

The RT6228A/B/C is an advanced constant on-time (ACOT®) mode synchronous buck converter. The main control loop of the RT6228A/B/C using an advanced constant on-time (ACOT®) mode control which provides a very fast transient response. The RT6228A/B operates from 4.5V to 23V input voltage and the RT6228C operates from 5.1V to 23V. For the RT6228A, the output voltage can be programmed between 0.6V to 5.1V.

Applications

Industrial and Commercial Low Power Systems
Computer Peripherals
LCD Monitors and TVs
Green Electronics/Appliances
Point of Load Regulation for High-Performance DSPs, FPGAs, and ASICs
