RT9205A - Richiek

RT9205A Dual Regulators - Synchronous Buck PWM DC-DC and Linear Controller

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 allo.
