The VQC15-Q48-T515 from CUI Inc. is a 15W isolated DC-DC converter designed for ITE (Commercial) applications. It features a wide 4:1 input voltage range, supporting either 9-36VDC or 18-72VDC depending on the specific model variant. This converter boasts an efficiency of up to 82% and provides a 5V output with ±15V dual outputs, capable of delivering 1500mA for the 5V and ±250mA for the ±15V.
Key electrical specifications include a nominal switching frequency of 300KHz, line regulation of ±0.2% max for single/dual outputs, and load regulation of ±1.0% max for single/dual outputs. It offers a voltage accuracy of ±1.0% for single and ±1.0% for dual positive outputs, and ±3.0% for dual negative outputs. The transient response for a 25% step load change is less than 500μsec.
Environmental and safety features include an operating temperature range of -25°C to +71°C and an isolation voltage of 500VDC minimum. The converter is housed in a compact 2x2x0.4 inch (50.8x50.8x10.2mm) package with six-sided shielding for EMI/RFI protection. Cooling is achieved through free-air convection. The case material is black coated copper with a non-conductive base.
