DC Switching Voltage Regulators

MP2188GQA-P Description

The MP2188GQA-P from Monolithic Power Systems (MPS) is a high-efficiency, dual-output synchronous buck regulator designed for compact, power-sensitive applications. This DC switching voltage regulator integrates two adjustable or fixed-output (0.8V to 5.5V) channels, each capable of delivering up to 3A of continuous current. With a 2.5V to 5.5V input range and a 1.2MHz switching frequency, it optimizes performance in space-constrained designs while minimizing external component count. Packaged in a 16-pin QFN and available in Tape & Reel (TR), it meets ROHS3 and REACH compliance, ensuring environmental and regulatory adherence.

MP2188GQA-P Features

• Dual-Output Flexibility: Supports two independent outputs, configurable as adjustable (0.8V–5.5V) or fixed (1.1V, 1.8V), ideal for multi-voltage systems.
• High Efficiency: Synchronous rectification reduces power loss, achieving peak efficiency for battery-powered and low-voltage applications.
• Compact Design: 1.2MHz switching frequency allows for smaller inductors and capacitors, saving PCB space.
• Robust Performance: 3A per channel with 5.5V max input ensures reliable operation under varying loads.
• Industry Compliance: ROHS3, REACH Unaffected, and ECCN EAR99 certified, with MSL1 (Unlimited) moisture sensitivity for extended shelf life.

MP2188GQA-P Applications

• Portable Electronics: Smartphones, tablets, and wearables benefit from its low-voltage, high-current capabilities.
• IoT Devices: Efficient power management for sensors, gateways, and edge-computing modules.
• FPGA/ASIC Power Supplies: Dual-output design simplifies multi-voltage rail generation.
• Industrial Systems: Suitable for automation controllers, PLCs, and embedded systems requiring stable, compact regulators.
