Murata MYMGK1R820GRSR-H Non-Isolated Point-of-Load DC-DC Power Converter Module

Function

Input voltage: 4.5–5.5V (typical 5V), adjustable output voltage: 0.7–1.8V, maximum output current up to 20A. It provides low-voltage, high-current and high-precision local power supply for core chips such as FPGA, CPU and ASIC.

Integrated with inductor, MOSFET, control IC and compensation circuits, it adopts mono-block structure without complicated peripheral components, which simplifies power circuit layout and saves PCB space.

It features high efficiency, low noise and excellent heat dissipation performance. It supports remote on/off control and remote sense function with fast load transient response, avoiding crash and malfunction of core chips caused by voltage fluctuation.

Operating temperature range covers -40℃ to +105℃ for industrial grade, ensuring stable power supply under high temperature and suitable for long-term continuous operation equipment.
