RT6256C Overview
The RT6256B/C is an advanced constant on-time (ACOT®) mode synchronous buck converter. The main control loop of the RT6256B/C using an advanced constant on-time (ACOT®) mode control which provides a very fast transient response. The RT6256B operates from 4.5V to 23V input voltage and RT6256C operates from 5.1V to 23V.
