Introduction

AI Translation

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.
