Product Overview
The 24V Micro Family by VICOR comprises advanced DC-DC converter modules designed to deliver efficiency, high power density, and reliable performance suitable for a range of applications, including industrial and process control, distributed power systems, medical equipment, Automated Test Equipment (ATE), communications, defense, and aerospace. These modules operate with an input voltage range of 18 to 36V, and offer isolated outputs ranging from 3.3V to 48V.
Key Characteristics and Benefits
With efficiencies up to 89% and power densities of up to 91 watts per cubic inch, these converters integrate Zero-Current Switching/Zero-Voltage Switching (ZCS/ZVS) technology to minimize noise and maximize efficiency. They are also parallelable, with N+M fault tolerance for scalable power solutions and can perform at 75% power down to 16V input after start-up.
Regulation, Protection, and Environmental Compliance
The modules provide tight regulation from +0.4% across no-load to full-load conditions. They can withstand input surges of 50V for 100ms and are specified with absolute maximum ratings including input-to-output isolation voltage of 3000VRMS. Additionally, the design ensures low-noise operation due to its ZCS/ZVS architecture. Available with F or G pin options, the modules are RoHS compliant, reflecting a commitment to environmental standards.
Thermal and Mechanical Specifications
The operational temperature range extends from -55°C to +100°C, with storage temperatures ranging from -65°C to +125°C. The units’ mounting specifications are detailed, including soldering temperature limits for both wave and hand-solder methods and mounting torque in inch-pounds or Newton-meters.
