RECOM Switching Regulator, 6.5 to 32V DC Input Voltage Range, 5V DC Output Voltage - R-78B-1.0 Series - R-78B5.0-1.0L


Looking for a reliable energy converter for your PCB? Choose this switching regulator from RECOM. It transforms input voltages between 6.5 and 32V DC to a steady output voltage of 5V DC, so it's a good choice for use in low-power applications. The compact dimensions of 11.5 (L) x 8.5 (W) x 17.5mm (H) make it suitable for installation in busy setups. It features continuous short-circuit protection with automatic recovery to protect your system against damage and reduce downtime in the event of a fault. Thanks to a mean time between failures of 6,584,000 hours at +25°C, this is a long-lasting choice.

Features & Benefits


• Wide operating temperature range between -40°C and +85°C for use in demanding conditions
• Non-conductive plastic case helps to reduce the risk of electric shocks
• Pins have a 90° orientation for side mounting, to suit installation in tight spaces

Applications


• Consumer devices
• Battery-powered systems
• Research and development labs

Do I need to use a heat sink with this device?


No. Thanks to the component's high efficiency of 88 to 93%, it wastes little energy as heat, so there's no need to use a heat sink.
