PQA50-D Series, Ultra-Compact 50 W DC/DC Converters


CUI's PQA50-D series 2 x 1” package is equipped with EMC shielding, precise voltage regulation, and high-efficiency figures across the entire input range

The PQA50-D is one of the industry’s smallest 50 W DC/DC converters. The series feature set makes it ideally suited for IT equipment, telecom and industrial systems. The DC/DC converter series is a low-cost, high-performance family with a 2 x 1 inch (50.8 x 25.4 mm) footprint, an industry standard size for less-powerful devices. It incorporates six-sided metal shielding for improved EMC performance and efficiency 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 to 36 VDC or 36 to 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 PQA50-D series include an operating temperature range of -40 to 85°C, remote on/off control, and voltage adjustability of +/- 10%.
