 Vicor Expands the Maxi, Mini, Micro Family of DC-DC Converters with a New 150-Volt Input Series that Simplifies 100/115Vac Front End Design Powerbox is delighted to announce Vicor’s new input series for the Maxi, Mini, Micro series of DC-DC converters. The new 150 V input series consists of 24 base models. 

The modules — which incorporate Vicor patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) — can be used in a variety of applications, including industrial and process control, power distribution controls, medical, instrumentation, communications, defense, and aerospace. “The new 150V Input series simplifies the AC front end design for applications that run solely off 100 or 115 V mains (e.g., US, Japan) because the converter input range matches the output of a simple rectified front end,” said Joe Sullivan, Product Marketing Manager.  Additionally, the low-noise ZCS/ZVS greatly reduces the design effort and filtering costs required for power converters to meet agency conducted emissions requirements. 

The 24 new models of the 150 V input series include eight standard output voltages (3.3, 5, 12, 15, 24, 28, 36, 48) in combination with three different package sizes (quarter brick, half brick, full brick) with output power ranging from 75 W up to 500 W depending on the model. The converters operate from 150 V nominal input, with an input range of 100 V to 200 V and efficiencies ranging up to 90%. 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 PowerBench™ tools which allow a customer to configure an infinite array of custom module designs on-line, and verify them in real time. The modules, which are optionally available in RoHS compliant models, are compact with a height above board of 0.43 inch (10,9 mm). The footprint for  the Maxi is 4.6 x 2.2 x 0.5 in. (117 x 56 x 12,7 mm); the Mini is 2.28 x 2.2 x 0.5 in (57,9 x 55,9 x 12,7 mm); and the Micro is 2.28 x 1.45 x 0.5 in. (57,9 x 36,8 x 12,7 mm).
