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 puters. 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 pensated 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 ponent size for saving board area. The RT9203/A also Features over voltage protection...
