R78Bxx 2.0 Series Switching Regulator

The Recom R-78Bxx series are highly efficient, non-isolated switching regulators. They offer a high-quality product at a low cost in production quantity. They are ideally suited to replace 78xx linear regulators, as well as being pin compatible.

The convertor has a high-voltage input range and there is no need for heat sinks, due to little energy being wasted. It has a wide input range with continuous short circuit protection and no external components are needed to work efficiently.

Features and Benefits

• Wide operating temperature of -40 to +70 °C at full load
• Pin compatible with TO220 linear regulators
• High efficiency, non-isolated, no need for heatsinks
• Requires no external components
• Continuous short circuit protection
• Low ripple and noise
• Compact size, ensuring space saving
• Positive to negative converter
