Changing up your current is a doddle with this DC-DC converter from RECOM. It takes a fluctuating 4.5 to 5.5V DC current and smooths out the kinks to give you a stable 5V DC output. This keeps your downstream kit running without a hiccup. Measuring just 19.6 (L) x 6 (W) x 10.2 (D) mm, the SIP-7 package is super-compact and fits into tight spaces. As the 1W converter provides 5.2kVDC of isolation for up to one minute and is reinforced with triple-insulated wires, it's a safe option that's suitable for use in medical settings.

• Through-hole mounting gives extra strength and security
• Wide operating temperature range between -40°C and +90°C to suit harsh industrial conditions
• Operates at 80% efficiency, so it wastes little energy as heat

• Manufacturing equipment
• Industrial power supplies
• Consumer electronics

To keep your supply consistent, you can use isolated DC-DC converters to break up ground loops, remove noise or steady a fluctuating voltage to an exact value.

This device has just one output, so it's a straightforward option.
