RT9218B中文资料12V Synchronous Buck PWM DC-DC and Linear Power Controller数据手册Richtek规格书

描述 Description

General Description
The RT9218B 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.
