Dual Regulator - Standard Buck PWM DC-DC and Linear
Power Controller
General Description
The RT9204 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 uses a 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 protects the converter and regulator by
monitoring the output under voltage.
