VICOR Mini Family 300V Input DC-DC Converter Module Datasheet

Category: Electronics, Other Semiconductors, Vicor Corporation

Product Overview

The VICOR Mini Family 300V Input DC-DC converter module integrates advanced power processing, control, and packaging technologies to deliver performance, flexibility, reliability, and cost-efficiency. With an actual size of 2.28 x 2.2 x 0.5 inches (57.9 x 55.9 x 12.7mm), this module is suitable for various applications, including off-line systems with auto-ranging or PFC front ends, industrial and process control, distributed power systems, medical, ATE, communications, defense, and aerospace.

Features & Benefits

The module has a wide DC input range of 180 to 375V and can withstand input surges of up to 400V for 100ms. The DC output voltage spans 2 to 48V and is programmable from 10 to 110% of its nominal value. With a regulation of +/-0.4% from no load to full load and efficiencies reaching up to 89%, these converters provide stable, efficient performance. Thanks to High-frequency Zero-Current Switching / Zero-Voltage Switching (ZCS/ZVS) technology, the modules operate quietly while maintaining high power density. Additional features include parallel operation with N+M fault tolerance, low noise levels, high efficiency, and a maximum operating temperature of 100°C under full load conditions.

Absolute Maximum Ratings

Key ratings include a -0.5 to +410VDC input voltage threshold, isolation voltages of 3000Vrms from IN to OUT, and various voltage thresholds for other connections. The modules can operate within an ambient temperature range of -55°C to +100°C, and have a storage temperature range of -65°C to +125°C. When soldering, wave soldering can reach 260°C for 5 seconds, with hand soldering permitted up to 390°C for 10 seconds. The recommended mounting torque is 5 in-lbs (0.57 N-m) for each pin.

Product Part Numbering and Variants

The product is customizable through various options represented in the part numbering system, such as output voltage (ranging from 2V to 48V), product grade temperature, output power (with variants from 100W to 250W depending on the output voltage), pin style finishes including RoHS compliant options, and baseplate configurations.

Electrical Specifications

The electrical characteristics encompass a broad operating input voltage from 180 to 375VDC, input surge withstand, undervoltage turn-on/off, and overvoltage turn-off/on. Module output specifications include the output voltage set point, line regulation, temperature regulation, power sharing accuracy, and programming range. The electrical properties guarantee optimal performance over the full operational range of input voltage, output load, and baseplate temperature.

Thermal Performance

The module exhibits excellent thermal performance with resistance values detailed for different interfaces, such as the baseplate to sink or baseplate to ambient. It also highlights a thermal capacity measurement – all of which ensure stable operation even in varied thermal conditions.
