CUI Inc has unveiled one of the industries smallest 50 W dc-dc converters, the PQA50-D. The series’ feature set makes it suitable for IT equipment, telecom and industrial systems. It 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.
The device also incorporates a 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 suitable for designs where minimising power consumption at various operating conditions is a priority.
The 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 also 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%.
