NCP5220 Dual Buck PWM Power Controller IC

The NCP5220 is a 3-in-1 PWM dual buck and linear power controller IC designed for advanced motherboard power management applications. This IC integrates dual buck controllers along with a linear VTT regulator capable of sourcing and sinking currents up to 2.0 A, making it suitable for memory and chipset power sections. The NCP5220 supports the use of all external N-channel power MOSFETs, offering improved efficiency and design flexibility.

Adjustable VDDQ and VMCH outputs through external resistor dividers allow precise voltage configuration based on system requirements. The VTT output accurately tracks at half of the reference voltage, ensuring stable termination power. This IC is widely used in professional repair and replacement scenarios involving laptop and desktop motherboards. Each NCP5220 supplied by OKSpare is physically verified and quality tested before dispatch to ensure reliable performance.
