RT6228C = K5

The RT6228  is an advanced constant on-time
(ACOT® ) mode synchronous buck converter. The main
control loop of the RT6228C 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.
8A, 23V Synchronous Step-Down Converter with 3.3V/5V LDO
