Product Overview

The MYMGK1R820FRSR-H is a MonoBK™ series high-temperature grade non-isolated Point-of-Load (POL) DC-DC power module launched by Murata, designed for high power density applications in extreme environments. With a wide input voltage range of 4.5V~8.0V, programmable output voltage of 0.7V~1.8V, and ultra-high output current of 20A, it delivers a stable output power of 36W. Adopting an ultra-small surface-mount package of 10.5×9.0×5.6mm, it features a maximum conversion efficiency of 93.2% and an extended operating temperature range of -40℃~105℃ (20℃ higher than the standard version). Integrated with multiple safety protection and fast load response functions, it complies with CISPR 32 Class B conducted emission standards, making it an ideal solution for high-temperature industrial equipment, outdoor electronics, and FPGA/CPU core power supply.

Technical Specifications

Typical Applications

• High-Temperature Industrial Control Equipment: The ultra-wide temperature range of -40℃~105℃ adapts to high-temperature industrial environments such as metallurgy and chemical engineering. The 20A high current output meets the core power supply needs of PLCs and servo drives. The over-temperature protection function prevents equipment damage in extreme temperatures, and positive logic On/Off control facilitates system integration.
• Outdoor Electronic Equipment: The wide-temperature characteristic withstands outdoor day-night temperature differences and extreme climates. The 4.5V~8.0V wide input adapts to outdoor power supply systems such as solar energy and storage batteries. The 36W power and fast load response meet the dynamic power needs of outdoor sensors and communication terminals, and the compact package saves internal space of equipment.
• FPGA/CPU Core Power Supply: 20A high current + 1.0A/μs fast load response accurately match the instantaneous power needs of core components such as FPGAs and CPUs. The 0.7V~1.8V programmable voltage perfectly adapts to different chip voltage specifications. The low ripple (1% of Vout) ensures stable operation of chips, and the high-temperature grade design adapts to high-temperature areas inside equipment.
• Data Communication & Telecom Equipment (High-Temperature Scenarios): The wide input voltage is compatible with distributed bus architecture, 93.2% high conversion efficiency reduces equipment energy consumption, and the 105℃ high-temperature tolerance adapts to outdoor chassis of communication base stations and high-temperature areas of computer rooms. Power Good signal feedback facilitates system status monitoring and fault diagnosis.
• Mixed Voltage Systems (Extreme Environments): The 0.7V~1.8V adjustable output voltage adapts to multi-voltage domain systems. The ultra-wide temperature design meets the needs of on-vehicle and outdoor mixed-voltage equipment. The compact package and surface-mount process facilitate high-density PCB layout, and multiple protection mechanisms improve system reliability in harsh environments.
