High-efficiency isolated DC-DC converters in compact rugged packages

CUI has expanded its portfolio of isolated DC-DC converters with the introduction of three new encapsulated models ranging from 10W to 30W. The PDQ10-D, PDQ15-D and PDQ30-D output 10W, 15W and 30W of power respectively in an industry standard 1 x 1 x 0.4 inch DIP five-sided, shielded metal case, making them ideal replacements for larger 1 x 2 inch modules. The PDQ-D models also feature a 4:1 input voltage range of 9 - 36VDC or 18 - 75VDC with high typical efficiencies up to 90%. The modules come with single regulated output voltages of 3.3, 5, 12 and 15VDC or dual regulated output voltages of ±5, ±12 and ±15VDC. Due to its wide -40C to +105C operating temperature range and encapsulated design, the PDQ-D series is suitable for convection-cooled equipment and harsh environments with target applications that include telecom, industrial, remote sensor systems and portable electronics. All PDQ-D models offer an input to output isolation of 1,500VDC and feature remote on/off control while single output models also offer output voltage trimming that allows for a ±10% adjustment of the nominal output. Protections for over voltage, input under voltage lockout and continuous short circuit are also included.
