1 .V / 5V / 4A VRPC-04C Series RoHS Compiant Nonisoated Industry standard pinout Fixed frequency High efficiency means ess power dissipation Optimized for cost Remote on/off Undervotage ockout Over current and short circuit protection Industria temperature range Description The Be VRPC-04C series modues are non-isoated, boost DC/DC power converters that operate from a nomina.v source. These converters provide an output votage of 5V and are packaged in an industry standard singe-in-ine footprint with 4A maximum output. Standard features incude remote on/off, over current and short circuit protection. A version of this converter is aso avaiabe without remote on/off. These products may be used amost anywhere 5V is required and a.v source is avaiabe. appications incude fie servers, routers, ine cards and other computing and communications equipment.
