APW8868C 8868 Power IC for Laptop Motherboard

Product Description

The APW8868C 8868 Power IC is an ANPEC semiconductor power-management controller designed for DDR2 and DDR3/DDR3L memory power supply circuits. It integrates a synchronous buck PWM controller for VDDQ power regulation and a 1.5A LDO section for VTT termination voltage.

This IC is used in compatible laptop motherboard circuits to regulate memory-related power rails and support stable RAM power delivery. It is a replacement component for motherboard-level repair when the original APW8868C IC is confirmed faulty.

Product Features

• ANPEC APW8868C power-management IC
• Designed for DDR2 and DDR3/DDR3L memory power supplies
• Integrated synchronous buck controller for VDDQ
• Integrated 1.5A LDO regulator for VTT
• Adjustable VDDQ output voltage
• Supports input power from 3V to 28V
• Built-in over-voltage and under-voltage protection
• Thermal shutdown and current-limit protection
• Compact TQFN 3mm × 3mm, 20-pin package

Compatible Models

This is a motherboard-level electronic component. Compatibility depends on the exact motherboard circuit and original IC marking rather than the laptop model alone.

Please verify the APW8868C marking and package layout on the original motherboard before ordering.

Compatible Part Numbers

• APW8868C
• 8868C (top-marking identification)

Important: APW8868B and APW8868C are separate variants. Do not assume they are interchangeable without checking the circuit design and datasheet.

Function of APW8868C IC

The APW8868C manages power supplied to DDR memory circuits. Its buck controller regulates the VDDQ supply, while its integrated LDO generates the VTT termination voltage and supports the VTTREF reference.

A faulty memory power controller may contribute to symptoms such as:

• Laptop not powering on.
• No display or failure during startup.
• RAM not being detected correctly.
• Memory-related motherboard power rail problems.
• Laptop restarting or failing during the boot process.

These symptoms can also result from faulty RAM, MOSFETs, capacitors, BIOS issues or other motherboard faults. Proper voltage and circuit testing is required before replacing the IC.

Installation and Repair Guidance

• Installation should be performed by an experienced motherboard technician.
• Confirm the original IC marking before replacement.
• Check the pin configuration and PCB footprint.
• Inspect surrounding MOSFETs, capacitors and memory power components.
• Verify the relevant power rails before and after replacement.
• Use suitable ESD protection and professional soldering equipment.

Warranty Details

No Warranty

Important Note

• Confirm that your original motherboard IC is marked APW8868C or 8868C before purchasing.
• Compare the package size, pin layout and component marking carefully.
• APW8868B and APW8868C should not be treated as interchangeable without technical verification.
• Incorrect IC installation or an incompatible replacement may damage the motherboard.
• This component is intended for motherboard-level repair by a qualified technician.
• Product images are for reference; actual component markings may vary by manufacturing batch.
• Please provide a complete delivery address, PIN code and active contact number when placing your order.

Frequently Asked Questions

1. What is the function of the APW8868C IC?

The APW8868C is a DDR memory power controller that regulates VDDQ and provides VTT termination voltage for compatible memory circuits.

2. Is APW8868C used on laptop motherboards?

Yes, it can be used in compatible laptop motherboard memory power circuits. Exact compatibility depends on the motherboard design.
