Description

TheRT9205/Ais 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 PWMcontrol for simplying design.An internal 0.8V reference allows the output voltage to be precisely regulated tomeet lowoutput 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).
