In the market for a compact PSU packing plenty of punch? Try this DC-DC converter from Traco Power. It takes inputs ranging between 4.5 and 5.5V DC and provides a steady load of ±5V DC. This makes it ideal for charging battery-boosted devices. The compact SMD10 footprint of 16.24 (L) x 8.4 (W) x 7.2mm (D) and 1W rating mean you're getting a high-power-density component that's a breeze to squeeze onto your PCB. Thanks to the unit's UL 94-V0-rated package, it tolerates a broad operating temperature from -40°C to +90°C and is flame-retardant, so won't contribute to a fire.

• Dual output device lets you connect two pieces of equipment to power
• Non-conductive housing and base means the device poses no shock risk
• Low ripple and noise of 120mVp-p max indicates minimal risk from EMI
• Mean time between failures of 2 million hours, so it's built to last

• Telecommunications networks
• Distributed power systems
• Digital interfacing

This DC-DC converter is isolated to 1.5kV DC on its input and outputs to keep you safe in case of voltage surges. It also comes with short-circuit protection to shield you and your equipment from common current faults.
