Preliminary RT9203/A Dual Regulators - Synchronous Buck PWM DC-DC and Linear Controller General Description The RT9203/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 8-pin package. The RT9203/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 RT9203/A also features over voltage protection (OVP) and under voltage lock-out (UVLO). Features l l l l l l l l l l l l Operates at 5V 0.
