HIP6302CB Multi-Phase PWM Controller IC

The HIP6302CB Charging / Multi-Phase PWM Controller IC is a key VRM controller used in older and mid-generation desktop motherboards, especially AMD K7/K8 platforms and early Intel Core systems. It manages the multi-phase MOSFET stages that supply regulated Vcore voltage to the CPU.

By controlling switching phases and balancing load across power stages, the HIP6302CB ensures:

• Stable CPU voltage
• Efficient power delivery
• Reduced heat on MOSFETs
• Protection during load transitions

This IC is commonly replaced when motherboards show:

• No power / no boot
• CPU not detecting
• VRM overheating
• System resets under load
• Burnt MOSFETs or unstable Vcore rails

Due to its role in the CPU VRM, the HIP6302CB is a frequent repair part in desktop motherboard service centers.

At OKSpare Nehru Place, the HIP6302CB is available in ready stock, quality tested, and supplied in wholesale or retail quantities for motherboard repair engineers.
