DC/DC Converter Family Adds High-Power Members

Expanding the company's 28V-input dc/dc converter family, the CB150D and CB225T are available with output voltages of 2, 3.3, 5, 5.2, 12, 15, 24, and 28 Vdc. Both models offer multiple independent 75W outputs designed for applications in the military, industrial, and aerospace arenas. Measuring 57.9 mm x 73.7 mm x 12.7 mm, the CB150D is a 150W device with two independent 75W output channels. The CB225T measuring 57.9 mm x 110.5 mm x 12.7 mm in size is a triple output module delivering 75W per channel. Both converters feature a wide input range from 16 to 40 Vdc, remote turn on/off (TTL), output over-voltage trim pins, over-voltage and over-current protection, and a fixed 500-kHz conversion and synchronization input. All models are available in I (unscreened) and M (screened) grades with efficiencies as high as 84%. Prices for the I-grade CB150D and CB225T are $495 and $675 each/50+, respectively.
