Compact 50W DC/DC converter cuts space & cost In telecomm, industrial, & ITE apps



Well-suited for use in IT equipment, telecom and industrial systems, the PQA50-D from CUI is one of the industry's smallest 50W DC/DC converters. The low-cost, high performance converter family has a 2 x 1 inch (50.8 x 25.4 mm) footprint an industry standard size for less powerful devices, and has a six-sided metal shielding for improved EMC performance.

With an operating efficiency of up to 93%, the converters maintain high efficiency figures across the entire input voltage range - including under light loads, making the PQA50-D series ideal for designs where minimizing power consumption at various operating conditions is a priority.

The single output isolated dc-dc converter modules feature a 2:1 input range and are available with an 18~36 Vdc or 36~75 Vdc input voltage range and 3.3, 5, 12, 15 or 24 Vdc output voltages. The series has 1500 Vdc input-to-output isolation and protections for output over voltage, short circuit, over load, and input under voltage.

The series offers precise voltage regulation, featuring load regulation of +/- 1% max. from 10% to 100% load and line regulation of +/- 0.5% max. Additional features of the new PQA50-D series include an operating temperature range of -40~85 C, remote on/off control, and voltage adjustability of +/- 10%.

The PQA50-D series is now available through distribution with prices starting at $85.12 for 100 pieces. OEM pricing is available upon request.
