RT6228A RT6228AGQUF K6= Marking K6= IC Power Management IC is a high-efficiency synchronous step-down (buck) converter designed for compact and reliable power regulation. It operates over a wide 4.5V to 23V input range and delivers adjustable output voltages from 0.6V to 5.1V, making it ideal for powering CPUs, chipsets, and logic circuits in motherboards, GPUs, and embedded systems.
The device integrates high-side and low-side MOSFETs for improved efficiency and reduced component count. It also features fixed-frequency PWM operation with fast transient response for stable and low-ripple output.
Comprehensive protection functions include Over-Current Protection (OCP), Under-Voltage Protection (UVP), and Over-Temperature Protection (OTP). Packaged in a compact QFN form factor, the RT6228A is identified by marking code “K6=” and delivers exceptional performance for high-density power designs.
