General Description

The RT6226A/B/C is an advanced constant on-time

(ACOTTM) mode synchronous buck converter. The main

control loop of the RT6226A/B/C using an advanced

constant on-time (ACOTTM) mode control which provides

a very fast transient response. The RT6226A/B operates

from 4.5V to 23V input voltage and the RT6226C operates

from 5.1V to 23V. For the RT6226A, 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
