MP5610GQG-P

Overview

The MP5610GQG-P is a dual-channel LCD bias power supply designed for smartphones and tablets. It operates with an input voltage range of 2.7V to 5.5V and utilizes a 1.2MHz switching frequency. The device integrates a boost converter for positive output regulation and a negative charge pump for negative voltage generation. It features peak current mode control, synchronous rectification, and a compact QFN-10 (1.4mm x 1.8mm) package.

Feature Summary

• Integrates a boost converter and negative charge pump powered directly from the positive conversion node for high efficiency.
• Provides excellent voltage tracking between positive and negative outputs through matched internal MOSFET on-resistance values.
• Includes comprehensive protection mechanisms such as input/output disconnect, cycle-by-cycle current limit, over-temperature shutdown, and over/under-voltage protection.

Applications

• Smartphone LCD panel bias power supplies
• Tablet display driver power systems

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging when ordering. Confirm RoHS compliance status via official documentation before integration. Ensure the design accommodates the specified thermal requirements for the QFN-10 package. Cross-reference the manufacturer datasheet for exact pinout configurations and recommended external component values to guarantee stable operation within the defined electrical parameters.

Selection Notes

Select this component for applications requiring small form factor LCD bias generation. The integrated synchronous rectification reduces PCB space requirements compared to discrete solutions. Consider the fixed 1.2MHz frequency for EMI management and inductor size optimization. Evaluate the programmable output capabilities against specific display voltage requirements to ensure adequate headroom and regulation accuracy.
