RT9214PS Description

Short technical summary and product information.

The RICHTEK RT9214PS is a high-efficiency synchronous buck PWM controller. It is designed to generate logic-supply voltages in PC-based systems and other applications requiring high performance, single-output DC/DC conversion.

 

This controller operates with supply voltages of 5V or 12V and features a fixed 300kHz oscillator frequency, providing an optimal balance between efficiency, external component size, and cost. It supports a full 0 to 100% duty ratio and includes internal soft-start and an adaptive non-overlapping gate driver.

 

The RT9214PS integrates control, output adjustment, monitoring, and protection functions into a single package. It offers adjustable over-current protection (OCP) that monitors the voltage drop across the RDS(ON) of the lower MOSFET, eliminating the need for a current sense resistor. The device is available in a surface-mount 8-SOP package.

 

Key applications include graphic cards, motherboards, desktop servers, IA equipment, telecommunication equipment, and high-power DC/DC regulators.
