Overview
The VICOR 24V Mini Family datasheet details a range of compact, high-efficiency DC-DC converter modules designed for a variety of applications including industrial and process control, medical, test equipment, communications, and defense. These modules offer an input voltage range of 18-36V and support various output voltages from 3.3V to 48V with exceptional power density, efficiency, and noise performance.
Key Features
Notable features of the Mini Family converter modules include isolated output, programmable output voltage ranging from 10-110%, load regulation within ±0.5%, and efficiencies up to 89%. The converters can operate up to 100°C at full load and have an input surge withstand capability of 50V for 100ms. For applications requiring multiple units, these modules are parallelable with N+M fault tolerance.
Applications and Compliance
The converter modules cater to a wide range of uses across various industries, such as automated test equipment (ATE), communication systems, and aerospace engineering. They employ zero-current and zero-voltage switching (ZCS/ZVS) architectures to minimize noise. Compliance with RoHS standards is ensured with specific pin options (F or G).
Physical and Electrical Characteristics
Physically, the converters measure 2.28 x 2.2 x 0.5 inches, with an above-board height of 0.43 inches. Electrical characteristics cover a comprehensive range, including under and overvoltage protection, line and temperature regulation, and power sharing accuracy. Also provided are absolute maximum ratings for external voltage applications for each output voltage available.
Thermal Specifications
The converters offer a thermal resistance as low as 0.14°C/Watt and a thermal capacity to handle varying environmental conditions. Supported baseplate temperature ranges from -55 to +100°C, accommodating extreme operational requirements.
Part Numbering and Product Grades
VICOR provides a part numbering system for selecting the appropriate module configurations, including output voltage, power grade, pin style, and baseplate design. Product grade temperatures are delineated by ‘PC’ numbers corresponding to operational and storage temperature ranges. Furthermore, the datasheet notes that output power varies depending on output voltage, ranging from 100W to 250W. Pin styles and finishes are distinguished by unique suffix codes.
Additional Notes
The datasheet emphasizes that the permissible load current must not be exceeded under normal, abnormal, or testing conditions. It additionally includes guidelines such as soldering temperatures and mounting torque specifications.
