CUI Intros Ultra-Compact DC-DC Converter
Ultra-Compact DC/DC converter.
Tualatin, OR — CUI Inc has introduced one of the industry's smallest 50W DC-DC converters, the PQA50-D. The converters' feature set makes them well suited for IT equipment, telecom and industrial systems.

The converter series is a low-cost, high-performance family with a 2 x 1-in. (50.8 x 25.4mm) footprint — an industry standard size for less powerful devices. It incorporates six-sided metal shielding for improved EMC performance and efficiency up to 93 percent.

The converters maintain high efficiency figures across the entire input voltage range — including under light loads, making the PQA50-D series suitable for designs where minimizing power consumption at various operating conditions is a priority. The single-output isolated DC-DC converter modules have a 2:1 input range and are available with an 18~36VDC or 36~75VDC input voltage range and 3.3, 5, 12, 15 or 24VDC output voltages.

The series has 1500VDC input-to-output isolation and protection for output over voltage, short circuit, over load, and input under voltage.

The converters offer precise voltage regulation, with load regulation of ±1 percent max., from 10 percent to 100 percent load and line regulation of ±0.5 percent 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 percent.
