The Recom R-78T series of DC-DC converters are compact, low profile SMD switching regulators. They have 3 standard pinning options: AC, AL and FC.
The R-78T series has a high efficiency of up to 95%, which means that these DC-DC converters do not require heatsinks or fans. The switching regulator can operate reliably between -40°C and 85°C without derating. These DC-DC converters are the ideal space-saving solution for portable battery-operated applications.

Seeking stable voltages to safely power your sensitive PCB-mounted equipment? The search is over now you've found this SMD-type DC-DC converter from RECOM. It steps down inputs across a broad range of 8 to 42V DC to deliver a carefully regulated output of 5V DC. The unit's tight line and load regulation of ±0.2% and load ±0.4% respectively means you can put money on predictable results. Thanks to the low noise values of typically 50mVp-p, max 100mVp-p, there's little risk of electrical spikes damaging connected devices.

• Open frame package helps keep device cool
• Compact dimensions of 23(L) x 29.4 (W) x 8mm (H) make it easy to fit onto your PCB
• Standard FC tray pinout configuration, so it's a piece of cake to solder in place
• Mean time between failures of 367,000 hours for a long service life
• ±2% typical accuracy for reliability

• Telecommunications hubs
• Consumer electronics
• Medical devices

This converter offers an efficiency between 85 and 92%, so you can trust it generates very little heat. This means you'll have no need for a heatsink and can safely rely on its free-air convection alone.
