RT9205/A
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 vo...
