Ordering Information
RT9204/A
General Description
The RT9204/A is a dual power controllers designed for
high performance graphics cards and computer
applications. The IC integrates a standard buck controller,
a linear regulator driver and protection functions into a
small 8-pin package.
The RT9204/A uses an internal compensated voltage
mode PWM control for simple application design. An
internal 0.8V reference allows the output voltage to be
precisely regulated to low voltage requirement. A fixed
600kHz oscillator reduce the component size for saving
board area.
The RT9204/A protects the converter and regulator by
monitoring the output under voltage.
