    Products Detail

    The RT9218 is a dual-output power controller featuring 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, it provides an optimum compromise between efficiency, external component size, and cost. The linear controller drives an external MOSFET for regulation and is adjustable via external resistors. It implements specific PGOOD sequence and indicator to conform to Intel's FSB_VTT power plane requirements. Over-current protection monitors 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, 300kHz Fixed Frequency Oscillator, Fast Transient Response, High-Speed GM Amplifier, Full 0 to 100% Duty Ratio, Internal Soft-Start, Power Good Indicator, Adaptive Non-Overlapping Gate Driver, Over-Current Fault Monitor on MOSFET, No Current Sense Resistor Required, Specific power good indicator for Intel® Grantsdale FSB_VTT power sequence, RoHS Compliant and 100% Lead (Pb)-Free
