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.

When you want an efficient power and conversion solution that can stand the heat, choose this DC-DC converter from RECOM. It steps down voltages from a broad 15 to 42V range so you get the stable, regulated supply of 12V DC needed to charge devices connected to your PCB. The unit's impressive efficiency between 92 and 95% means it wastes minimal energy as heat. This means you don't need to add a heatsink to your setup and can rely on free air convection to keep everything running cool. Thanks to a safe operating temperature range of -40°C to +85°C, this is a bit of kit you can count on in harsh environments.

• Standard AL tray pinout configuration for simple assembly
• Compact dimensions of 23 (L) x 27.2 (W) x 10mm (H) make it easy to fit onto your PCB
• Mean time between failures of 367,000 hours means you can count on a long service life

• Photovoltaic arrays
• Wind engines
• Telecommunications networks

This DC-DC converter offers tight line and load regulation of ±0.2% and ±0.4% respectively, so you can trust you're always getting precise conversions very close to the nominal values described.
