50W DC/DC converter in a 2 x 1-in. package

November 06, 2013 // By Graham Prophet
Reducing occupied board space in telecommunications and industrial applications, CUI's 50W product offers EMC shielding, precise voltage regulation and high efficiency figures across the entire input range.

PQA50-D occupies a 2 x 1 inch (50.8 x 25.4 mm) footprint – which is an industry standard size, but for less powerful devices, CUI says. 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.

The single output isolated DC/DC converter modules have 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. It achieves 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 to 85 °C, remote on/off control, and voltage adjustability of ±10%. Prices are from $85.12 (100).
