MP2625GL-Z

Overview

The MP2625GL-Z is a single-cell lithium-ion switching charger from Monolithic Power Systems, designed for portable devices like tablets. It features an input voltage range of 4V to 14V and supports up to 2A charging current. The device integrates synchronous buck regulation with NVDC power path management, allowing simultaneous system powering and battery charging. Key electrical parameters include a 1.6MHz switching frequency, 3.8mA operating supply current, and operation within -40°C to +125°C. It utilizes a QFN-20 package.

Feature Summary

• Integrates synchronous buck converter for efficient power conversion without external blocking diodes or sense resistors.
• Provides intelligent NVDC power path management to prioritize system load while charging the battery.
• Includes five control loops: input current limit, input voltage limit, constant charge current, full voltage control, and thermal fold-back protection.
• Supports USB 2.0/3.0 and AC adapter inputs with programmable input current limits.

Applications

• Single-cell lithium-ion battery charging in tablet computers
• Portable electronic devices requiring simultaneous system operation and battery charging
• USB-powered consumer electronics with high-efficiency charging requirements
