Vicor, Micro DC-DC converters

Mid-Power 24Vin Micro Modules Combine Performance and Cost Advantages

Vicor had added seven mid-power Micro DC-DC converters to its high-density 24Vdc input family: 50W models at 3.3, 5, 12, 15, 24, 28, and 48Vout. The modules — which incorporate Vicor's low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) — are appropriate for power system applications in industrial and process control, distributed power, medical, ATE, communications, defence, and aerospace.

The addition of these modules doubles the size of the high-power density 24Vin Micro family, which previously consisted of 75W at 3.3Vout and 100W at 5, 12, 15, 24, 28, and 48Vout. The converters operate from 24V nominal input, with an input range of 18V to 36V, and will operate down to 16V after startup. Efficiencies range up to 89% for the higher output voltages.

The modules, which are RoHS compliant (with F or G pin option), are 57.9 x 36.8 x 12.7mm in size with a height above board of 10.9mm.

These new mid-power Micros offer customers a cost-effective solution for applications that do not require the full-power capability of the Micro module, but would benefit from the low-noise performance and full feature set provided by the Micro platform.
