RECOM DC-DC Converter, 2200μF Maximum Capacitive Load, 10GΩ Minimum Isolation Resistance - RO Series - RO-053.3S


Make irregular power supply to your PCB-linked parts a thing of the past with this DC-DC converter from RECOM. It steps down 5V DC inputs to deliver a 3.3V DC output that's just right for light-duty components like LED lamps. For extra safety, it puts up a 1kV isolation barrier between the input and output, so you're not caught unawares by sudden power spikes. Thanks to its non-conductive plastic housing, this unit holds its own against impact, making it suitable for use in harsh environments. The material is also flame-resistant and stops burning in 10 seconds or less, so it won't help spread fire.

Features & Benefits


• Through-hole mounting achieves a secure connection to your circuit, making it suitable for vibrating systems

• Efficiency of 75% for minimal energy loss to heat

• Integrated short-circuit protection for electrical safety

• Compact dimensions of 11.5 (L) x 6.0 (W) x 10.0mm (D) for installation in setups with limited space

Applications


• Electrical workshops

• Measurement and instrumentation devices

• Mobile phones and tablets

What kind of pinout design does this converter have?


This unit has a standard SIP-4 pinout design, which makes it easy to integrate with other components on a circuit board.
