Dual Converter Powers FPGAs, DSPs

Calex Manufacturing announces the HD Dual Series of dc-dc converters, which offers seven different combinations of 1.5-V, 1.8-V, 2.5-V, 3.3-V and 5-V outputs. This flexibility enables a designer to supply both core and I/O processor voltages with one converter. Regardless of the output voltage pair selected, each voltage is independently regulated and can be individually trimmed to ±10%.

Fully isolated to 1500 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 overvoltage, undervoltage and reverse polarity protection.

These converters are packaged in a 2.28-in. × 2.4-in. encapsulated case with an aluminum base plate for excellent thermal performance. The operating temperature range for the HD series is -40°C to 100°C at the base plate. MTBF is greater than 1 million hours per Bellcore method 1, case 1. Positive and Negative On/Off logic are available, and the part offers a low idle current of just 2 mA. On power up, the turn on overshoot is 0%.

Pricing on the HD Dual is well under $100 for 1000 piece quantities.
