RT9218PS Description

Short technical summary and product information.

The RICHTEK RT9218PS is a versatile dual-output controller designed for generating logic-supply voltages in PC-based systems. It integrates a synchronous buck PWM controller and a linear controller, offering flexibility for various power management needs.

 

This device operates with a 5V or 12V supply voltage and features a fixed 300kHz oscillator frequency, providing an optimal balance between efficiency and component size. It supports a full 0 to 100% duty cycle for the buck controller and includes internal soft-start and adaptive non-overlapping gate drivers. The linear controller is designed to drive an external MOSFET for regulation, adjustable via external resistors.

 

Key features include an over-current fault monitor that eliminates the need for a current sense resistor and a specific power good indicator designed to meet Intel Grantsdale FSB_VTT power sequence requirements. The RT9218PS is available in a 14-SOP package, suitable for surface mount applications.

 

Applications for the RT9218PS include graphic cards, motherboards, desktop servers, IA equipment, and telecommunication equipment, making it a robust solution for high power DC-DC regulation.
