Le blog de l'entreprise Mingjiada Electronics MP1654 Power Chip: A High-Efficiency Synchronous Buck Converter Specifically Designed for Powering FPGA/SoC Cores and Industrial DC-DC Buck Applications

Against the backdrop of the rapid advancement of electronic devices towards miniaturisation and high integration, the selection of power management integrated circuits (PMICs) is of paramount importance. Shenzhen Mingjiada Electronics Co., Ltd. is now offering for global supply and actively seeking to purchase at a premium price a flagship product from MPS (Monolithic Power Systems, US-based Xinyuan) – the MP1654 series of synchronous buck DC-DC converters. Thanks to its outstanding performance, this chip is particularly well-suited to applications with stringent space and efficiency requirements, such as powering FPGA/SoC cores, industrial automation control, network communication equipment and portable IoT devices.

Key product advantages: compact package, high current, high efficiency

The MP1654 is a fully integrated, high-frequency, synchronous rectification step-down switching regulator that incorporates power MOSFETs with low on-resistance (RDS(ON)) (47 mΩ on the high side and 28 mΩ on the low side). It is capable of delivering a continuous output current of up to 4 A across a wide input voltage range of 4.5 V to 16 V, whilst stabilising the output voltage at levels as low as 0.6 V.

Key Electrical Parameters

Switching frequency: 1.1 MHz (MP1654/MP1654N) or 600 kHz (MP1654L) options, allowing the use of small inductors.

Quiescent current: Just 110 μA; combined with Power Save Mode (PSM), this significantly improves light-load efficiency.

High-precision feedback: Feedback accuracy of ±1 per cent at room temperature and ±1.5 per cent over the full temperature range ensures stable output voltage.

Package: Ultra-compact SOT563 package (1.6 mm × 1.6 mm), maximising PCB space savings.

Key Applications: Safeguarding High-Performance Digital Circuits

Thanks to its fast transient response and precise output voltage regulation, the MP1654 is the ideal power supply solution for the following applications:

FPGA/SoC Core and I/O Power Supply: In MPS’s official reference designs, the MP1654 is specifically used in the power tree solutions for Virtex US+ FPGAs and Zynq UltraScale+ RFSoCs. Its COT (Constant On-Time) control technology delivers ultra-fast load transient response, meeting the stringent requirements of FPGA cores for current surges during logic transitions.

Industrial automation and control: Suitable for PLCs, factory automation sensor nodes and industrial instruments; its wide input voltage range enables stable operation in 24V or 12V bus environments.

Network Communication Equipment: Used for board-level power conversion in devices such as routers, switches and base stations; its high efficiency helps reduce the overall temperature rise of the equipment.

Consumer Electronics and IoT: Suitable for smart door locks, digital set-top boxes, security surveillance systems and low-power IoT modules based on platforms such as the ESP32.
