RT9218 5V/12V Synchronous Buck PWM DC/DC and Linear Power Controller General Description The RT9218 is a dual output with one synchronous buck PWM and one linear controller.
The part is proposed to generate logic-supply voltages for PC based systems.
The high-performance device includes internal soft-start, frequency-compensation networks, power good signaling with specific sequence, and it comes all of the logic control, output adjustment, power monitoring and protection functions into a small footprint package.
The part is operated at fixed 300kHz frequeny providing an optimum compromise between efficiency, external component size, and cost.
The linear controller is implemented to drive ...
