MPQ2171GJ-AEC1-Z: High-efficiency miniaturised solution  

Technical specifications  

The MPQ2171GJ-AEC1-Z is a miniaturised synchronous buck converter designed for space-constrained applications, featuring a TSOT-23-8 ultra-thin package with dimensions of just a few square millimetres. The device supports a wide input voltage range of 2.5V to 5.5V, making it particularly suitable for 3.3V or 5V bus-powered systems. It delivers a maximum output current of 1A and can be adjusted to as low as 0.6V, meeting the low-voltage power requirements of modern microprocessors and FPGAs. A switching frequency of up to 2.6MHz enables the use of miniature inductors and ceramic capacitors, significantly reducing the PCB footprint of the power solution.

It uses a QFN package (3mm × 3mm × 0.8mm) to achieve an output current capability of up to 3A in a compact space. The device supports an input voltage range of 3.3V to 18V, covering standard industrial 12V power systems; the output voltage can be flexibly configured within a range of 0.8V to 30V to meet the needs of various industrial loads. Its high switching frequency of 2MHz allows for the use of smaller filtering components, making it particularly suitable for space-constrained high-density power designs.

MPQ4320GLE-AEC1: Ultra-Low Power Automotive-Grade Converter

Designed specifically for automotive electronics

The MPQ4320GLE-AEC1 is an AEC-Q100-certified automotive-grade synchronous buck converter designed for the harsh environments of vehicle electronic systems. The device is packaged in a QFN-12 (3mm × 4mm) package with side tin plating to enhance soldering reliability. Its input voltage range spans 5V to 36V, with a 42V load dump tolerance and 3.1V cold start capability, enabling it to withstand voltage transients in automotive power systems. Within the wide temperature range of -40°C to +150°C, the device can sustain a 0.5A output current, meeting the demands of high-temperature environments such as engine compartments.

MPQ4324EGDE-AEC1: High-current automotive power core

High-performance power conversion

The MPQ4324EGDE-AEC1 is an automotive-grade 4A synchronous buck converter in a compact QFN-12 (2mm × 3mm) package, delivering efficient power conversion in a minimal space. The device supports a wide input range from 3.3V to 36V, with 42V load dump protection capability, and the output voltage can be flexibly configured between 0.8V and 34.2V. The switching frequency can be programmed within the range of 350kHz to 2.5MHz, allowing designers to optimise the balance between efficiency, EMI performance, and component size. The internally integrated 70mΩ high-side MOSFET and 50mΩ low-side MOSFET achieve up to 95% conversion efficiency.
