CUI’s VX78 and VXO78 series of non-isolated DC-DC converters are high-performance alternatives to linear regulators. These non-isolated converters are pin out compatible with linear regulators. The VX078-500 and VX078-1000 converters are open-frame, whereas the VX78-1000 and VX78-500 are encapsulated converters. Both series feature 500mA and 1A current options. All of these models do not require a heatsink and are ideally suited for positive and negative output applications. These DC switching regulators deliver efficiencies up to 96%, a wide input voltage range from 4.75V to 36V, and low ripple and noise.
