Calex Manufacturing Intros HD Dual Series DC Converters

Calex Manufacturing Co. Inc. (Concord, CA) announced the addition of the HD Dual Series to its offering of dc-dc conversion solutions. Seven different combinations of 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5 V are available as output voltages. Regardless of the output voltage pair selected, each voltage is independently regulated and can be individually trimmed to ±10%.

Fully isolated to 1,500 Vdc, the HD Dual Series supports input-voltage ranges of 18 V to 36 V and 36 V to 75 V. Each output is rated for up to 10 A of output current, with a combined maximum power level of 75 W, and both outputs can be operated down to no-load current without damage to the part. Pulse-by-pulse current limiting and short-circuit protection are included as standard options, as are over-voltage under-voltage and reverse-polarity protection.

The converters are packaged in a 2.28 in x 2.4 in encapsulated case with an aluminum baseplate. The operating temperature range for the HD Series is -40 °C to +100 °C at the baseplate. The mean time between failure is greater than 1,000,000 hours, and the part offers a low idle current of 2 mA. On power-up, the turn on overshoot is 0%.

The converters are backed with a five-year warranty. Pricing on the HD Dual is under $100 for 1,000-piece quantities. Samples are shipping now, and production quantities are available with a lead time of four to six weeks.
