Recom 5 Output Switching Regulator 75V, 500mA, SIP Package, R-78HB6.5-0.5

The Recom R-78HB6.5-0.5 is a high-performance 5 output switching regulator specifically designed for versatile power management in industrial, automotive, aerospace, and battery-powered systems. Delivering a regulated 6.5V DC output at up to 500mA current across five independent channels, it provides reliable voltage conversion and distribution from a wide input range of 9V to 75V DC.

Equipped with a SIP package form factor measuring just 17.5mm x 11.5mm x 8.5mm and weighing only 4g, the device is optimized for space-efficient PCB design and quick integration into electronic assemblies. Advanced switching regulator technology results in high efficiency, with a typical value of 84%. This reduces energy loss as heat, allowing deployment without a heat sink even in continuous operation scenarios.

Engineered for stability, the regulator offers low ripple and noise (20mV Pk-Pk), maintaining clean power for sensitive electronics and minimizing interference. Robust operational reliability is provided by a wide operating temperature range, from −40°C up to +85°C, and a mean time between failures exceeding 7 million operations at +25°C. The output accuracy is typically maintained within ±2%, and load regulation within ±0.6%, ensuring tight voltage control under variable loads.

Safety features include continuous short-circuit protection, effectively shielding devices and operators from hazardous excess currents. The high relative humidity rating (up to 95%) permits installation in moist or demanding industrial environments.

Common applications for the R-78HB6.5-0.5 include automotive electronics, aerospace control systems, and industrial battery-powered equipment where dependable DC voltage regulation across multiple outputs is necessary.

The combination of features makes this Recom switching regulator an excellent choice for engineering projects requiring compact, efficient, and robust voltage conversion. Professionals in industrial automation, laboratory instrumentation, telecommunications, and embedded control benefit from its stability and flexible input support.
