Category: Electronics, Other Semiconductors, Vicor Corporation

Product Overview and Features

The VICOR Micro Family 28V DC-DC Converter Module is designed for industrial and process control, distributed power, medical equipment, automated test equipment (ATE), communications, defense, and aerospace applications. It features a DC input range of 9V to 36V, with a programmable output ranging from 10% to 110% of the nominal output. The converter’s input surge withstands 50V for 100ms. This unit provides DC outputs from 3.3V to 48V and maintains high efficiency up to 81%. Furthermore, the module operates at temperatures up to 100°C under full load, with a power density of up to 60W per cubic inch. It also features a low-profile design, standing just 0.43 inches above the board.

Product Specifications

Key specifications for this DC-DC converter module include regulation within ±0.2% from no load to full load and isolation voltage ratings between input to output (3000Vdc), input to base (1500Vdc), and output to base (500Vdc). The module is also designed with a low-noise Zero-Current Switching (ZCS) and Zero-Voltage Switching (ZVS) architecture, enhancing energy efficiency. For easy integration into environmental compliance programs, the module is RoHS Compliant with an F or G pin option. The product’s absolute maximum ratings cover input and output voltages, operating and storage temperatures, pin soldering temperatures, and mounting torque.

Part Numbering and Options

A variety of product grades are available to suit different temperature ranges and storage conditions. The part numbering system reflects options for output voltage, power output, pin style and finish, plus baseplate configuration. The document notes that some configurations may not be available and that product images might not showcase current product markings. High-frequency ZCS/ZVS switching featured in these modules is credited for their high-efficiency performance. Options include different voltage outputs, such as 3.3V, 12V, and up to 48V variations, with associated power ratings from 50W to 100W.

Electrical Characteristics

The module’s electrical characteristics specify the operational range of input voltage, output load, and baseplate temperature. It details input specifications like operating input voltage range, input surge withstand, under and overvoltage turn-off thresholds, and disabled input current. The output specifications include precision aspects such as output voltage setpoint, line regulation, temperature regulation, and power-sharing accuracy. A detailed analysis of thermal resistance and capacity is provided, incorporating baseplate to sink and baseplate to ambient efficiency. The document is thorough in describing these specifications to ensure accurate application integration.
