Vicor Expands Family of 300V Input Mini Modules

The Brick Business Unit of Vicor Corp. announced the addition of nine mid-power Mini dc-dc converters to the 300Vdc input family: a 100W model at 2 and 3.3Vout, 150W models at 5, 12, 15, 24, 28, 36, and 48Vout. The modules – which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) – can be used in a variety of applications, including off-line systems with auto-ranging front ends, industrial and process control, distributed power, medical, ATE, communications, defense, and aerospace. Low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements.

With these new entries, the 300Vin Mini family now comprises 17 models with output voltages spanning 2 to 48Vdc and power levels from 100 to 250W. The converters operate from 300V nominal input, with an input range of 180 to 375V. Efficiencies range up to 89% for the higher output voltages. These models are available in five different environmental grades, with six different pin options and three baseplate options. They can be also be configured in any combination using Vicor’s PowerBench™ tools which allow a customer to configure an infinite array of custom module designs on-line, and verify them in real time, at the company’s website.

The modules, which are optionally available in RoHS compliant models, are a compact 2.28 x 2.2 x 0.5 inch (57,9 x 55,9 x 12,7mm) in size with a height above board of 0.43 inch (10,9mm).

Pricing for the 300Vdc Mini models begin from as low as $87 USD (5V, 150W, E Grade) in 100-piece quantities. Lead times can be as short as three weeks for prototype quantities.
