Product Overview
The Micro Family 28V Wide Input is a series of DC-DC converter modules that offer efficient power conversion for a range of industrial and high-reliability applications. These modules are noted for their compact size, namely 2.28 x 1.45 x 0.5in, and utilize advanced power processing techniques to optimize performance.
Features & Benefits
The converter modules offer a DC input range from 9 to 36V and can withstand input surges of 50V for 100ms. The DC output voltage spans from 3.3V to 48V, with the possibility for programmable outputs ranging from 10% to 110%. These modules boast high regulation accuracy (+0.2% from no load to full load) and an efficiency rate of up to 81%. Power density is high at 60W per cubic inch, and the modules feature a low-profile design, standing at 0.43in above the board when mounted.
Applications
Suitable applications include industrial and process control, medical and test equipment, communications, and military and aerospace contexts, which benefit from the module’s reliability, efficiency, and design tailored for distributed power systems.
Absolute Maximum Ratings
The maximum operating temperature is 100°C under full load conditions. The modules have been tested to ensure durability, featuring isolation voltages of 3000V from input to output, and different grades indicating operating and storage temperatures, including an M-Grade for high-reliability military use.
Low-Noise and Efficient Architecture
The Modules feature low-noise, Zero-Current Switching (ZCS), and Zero-Voltage Switching (ZVS) architecture that improves efficiency and reduces noise, which is critical for sensitive applications.
Compliance and Configurability
VICOR’s converter modules are RoHS compliant with specific pin options, adaptable for parallel operation with N+M fault tolerance, indicating their suitability for building robust power systems. Baseplates come in slotted, threaded, and through-hole variations for various mounting requirements.
Part Numbering and Product Grades
Part numbers, such as V28C1ZT100BL2, determine the product type, output voltage, product grade (temperature handling capabilities), output power, pin style and finish. Note that some configurations may not be readily available, and attention to product-grade temperatures and pin style finishes, such as Tin/Lead or RoHS Gold, are crucial when selecting the appropriate module for specific applications.
