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).
