Reviews
Category: RT IC Richtek
Description
RT6220A RT6220AGQUF 6j= Marking 6J= IC Power Management IC is a high-efficiency synchronous step-down (buck) converter designed to provide a compact, reliable power solution for digital and computing applications. It operates over a wide 4.5V to 23V input voltage range and delivers a precisely regulated low-voltage output, ideal for powering chipsets, processors, and logic circuits.
This device integrates internal high-side and low-side MOSFETs for efficient operation and reduced external component count. The RT6220A supports fixed-frequency PWM control, enabling excellent line and load regulation, fast transient response, and low output ripple.
It includes robust protection features such as Over-Current Protection (OCP), Under-Voltage Protection (UVP), and Over-Temperature Protection (OTP). Packaged in a compact QFN form factor and identified by marking code “6J=”, this IC is widely used in motherboards, graphic cards, and industrial embedded systems.
