RECOM DC-DC Converter, Continuous Short-Circuit Protection, SIP-8 Package - RSO Series - RSO-053.3S


When you're seeking a safe industrial power and conversion solution, turn to this RECOM DC-DC converter. Its broad 2:1 voltage range means it steps down inputs ranging between 4.5 and 9V DC and transforms them to a stable regulated supply of 3.3V DC that's handy for powering sensitive battery-run devices. The unit offers tight line and load regulation of ±0.2% and ±0.4% max, so you get the close control over input and output values needed for predictable results. Thanks to its continuous short-circuit protection, you can also rest assured it shields you and your equipment against common current faults too.

Features & Benefits


• Flame-retardant package material means it won't contribute to the spread of flames in case of fire
• Remote on-off function gives you control from a distance
• Low ripple and noise levels of 50mVp-p, so you get stable behaviour with minimal EMI from noise
• Operates safely in temperatures from -40°C to +85°C to suit industrial settings

Applications


• Electric vehicles
• Smart lighting systems
• Telecommunications networks
