RECOM Switching Regulator, 84% Maximum Efficiency, 0.4W Internal Power Dissipation - R-78-1.0 Series - R-783.3-1.0


Use this switching regulator from RECOM to maintain a steady input voltage to your appliances. It's a DC-DC power converter that changes a varying voltage to a fixed 3.3V DC output voltage, making it ideal for use in appliances that could be damaged by power fluctuations. This unit works with input DC voltages ranging between 4.75 and 18V, meaning it's suitable for use in circuits where different components all draw power from the same source.

Features & Benefits


• Output current of 1A for low heat dissipation
• Functions in temperatures between -40°C and +85°C for use in demanding conditions
• Three terminal pins for easy mounting on your PCB
• 3.3V DC output voltage, suitable for use with your low-powered to medium-powered appliances

Applications


• Telecommunications equipment
• Electronic appliances
• Robotics and automation systems

Will my appliance be protected against a power surge?


Yes, this component comes with integrated short-circuit protection, which safeguards your appliances from damage caused by a power surge.

Can I use this device at any input voltage?


To ensure this device works properly, it's important not to overload the circuit with voltages above its maximum threshold of 18V DC.
