The UP1714Q (also marked UP1714QQDD) is a highly integrated PWM power management controller IC in a QFN-16 package, designed for efficient voltage regulation in high-current power rails. This controller is widely used on laptop motherboards, compact desktop boards, and GPU VRMs where a small footprint and precise power delivery are critical.
Engineered by uPI Semiconductor, the UP1714Q supports flexible multi-phase power control, enabling stable supply to core rails such as CPU or GPU Vcore, ensuring reliable system operation under varying loads. This IC is often replaced during repairs involving boot failure, unstable power, or sudden shutdown issues linked to the primary power stage.
