DC to DC Power Supplies (Converters)
Dual Regulators are suited for graphics cards and PCs.
Press Release Summary:
Supplied in 14-pin package, RT9205/A RoHS-compliant dual-output power controllers integrate synchronous buck controller, linear controller, and protection functions. Internally compensated voltage mode PWM control simplifies design, and internal 0.8 V reference enables precise regulation of output voltage. Also, fixed 300 kHz oscillation frequency reduces component size for conserving board space. Other features dynamic 0-100% duty cycle.

RT9205/RT9205A : Dual Regulators - Synchronous Buck PWM DC-DC and Linear Controller
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).
