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

RECOM Switching Regulator, Vibration-Resistant, 6.6W Power Rating - R-78B-2.0 Series - R-78B3.3-2.0


If your circuit's receiving excess current, take it down a notch with this switching regulator from RECOM. The unit steps down a wide input voltage range between 4.75 and 32V DC to a safe output level of 3.3V DC. Need to mount it? The soldering pins mean you can attach it to the underside of your board in a flash. Thanks to its built-in resistance to vibration, you can count on this unit to hold firm when things get shaky.

Features & Benefits


• Pin-compatible with TO220 linear regulators for use with legacy devices
• Built-in short-circuit and over-temperature protection for durability in harsh conditions
• Low ripple and noise of 50mV Pk-Pk for minimal signal disruption
• Efficiency rating of 92% reduces heat waste, eliminating the need for a heatsink

Applications


• HVAC systems
• Digital cameras
• Computer peripherals
• Telecommunications
