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 18~36 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 PQA50-D series include an operating temperature range of -40~85°C, remote on/off control, and voltage adjustability of ±10%.

Availability and Pricing

Availability for the PQA50-D series is 8-10 weeks.  The dc-dc converters fit in a 2 x 1 inch ultra compact package with a six-sided shielded case. The operating temp range is -40~85°C.  Prices start at $85.12 for 100 pieces through distribution.
