Ordering Information
RT9205/A
General Description
The RT9205/A is a dual-output power controllers designed
for high performance graphics cards and personal
computers. The IC integrates a synchronous buck
controller, a linear controller and protection functions into
a small 14-pin package.
The RT9205/A uses an internal compensated voltage
mode PWM control for simplying design. An internal 0.8V
reference allows the output voltage to be precisely
regulated to meet low output voltage requirement. A fixed
300kHz oscillation frequency reduces the component size
for saving board area.
The RT9205/A also features over voltage protection
(OVP) and under voltage lock-out (UVLO).
