    Products Detail

    The RT9218 is a dual output controller with one synchronous buck PWM and one linear controller. It includes internal soft-start, frequency-compensation networks, power good signaling with specific sequence, and integrates logic control, output adjustment, power monitoring, and protection functions in a small footprint package. Operated at fixed 300kHz frequency for optimal efficiency, component size, and cost compromise. The linear controller drives an external MOSFET for regulation and is adjustable via external resistors. Features specific PGOOD sequence for Intel® FSB_VTT power plane requirements and adjustable over-current protection monitoring voltage drop across the lower MOSFET's RDS(ON).

    Key Features

    • Operating with 5V or 12V Supply Voltage
    • Drives All Low Cost N-MOSFETs
    • Voltage Mode PWM Control
