Product Description

The MPM4841B power module, developed by Murata, is a high-efficiency DC-DC converter designed for industrial automation, telecom infrastructure, and IoT systems. This compact power supply accepts a wide input voltage range of 4.5–36V DC, delivering up to 4A output current with a configurable output voltage (0.8–6V). It integrates dual-phase synchronous rectification, enabling 95% peak efficiency while operating in temperatures from -40°C to +125°C. The MPM4841B supports PMBus communication for real-time monitoring and adjustment of voltage, current, and fault parameters. Its 7.5mm x 11.5mm x 3.2mm package simplifies integration into space-constrained designs. Key advantages include ultra-low output ripple, overcurrent/overvoltage protection, and thermal shutdown, though it lacks onboard energy storage or display interfaces. Optimized for high-density power delivery in harsh environments, this module excels in reliability but requires external components for advanced sequencing or redundancy.
