25-W 1- x 1-in. dc/dc converter offers 2:1 input

The QMS series of dc/dc converters offers up to 25 W of regulated output power in a 1 x 1-in footprint. The series offers a 2:1 input range with nominal input voltages of 12, 24, and 48 Vdc. Single outputs offered are 3.3, 5, 12, and 15 Vdc. Dual outputs are ±12 and ±15 Vdc.

The dc/dc converters operate with efficiencies as high as 90%. They feature remote on/off, output trim, and short circuit protection. The operating ambient temperature range extends from -40° to +50°C with no de-rating. The unit is encapsulated with a thermally conductive potting compound in a six-sided metal case.
