300V Micro Family DC-DC Converter Module Datasheet

Category: Electronics, Other Semiconductors, Vicor Corporation

The 300V Micro Family DC-DC Converter Module datasheet provides comprehensive information about a line of high-performance converter modules designed for a wide range of applications. They are specifically tailored to work within DC input ranges of 180 to 375V, making them suitable for systems that necessitate auto-ranging or Power Factor Correction (PFC) front ends.

These applications include industrial and process control, medical equipment, Automated Test Equipment (ATE), communication systems, defense, and aerospace applications. This family of converters is characterized by their high efficiency, reaching up to 90%, and a power density of up to 90 watts per cubic inch.

Key Features & Benefits

The modules are capable of providing isolated DC outputs ranging from 3.3V to 48V and feature programmability from 10% to 110% of the rated output voltage. They assure tight regulation with a variance of only ±0.5% across the full load spectrum, from no load to full load.

Moreover, the converters are designed to withstand input surges of up to 400V for 100ms and maintain operational integrity up to a maximum temperature of 100°C at full load. The compact size of the modules allows for minimal space usage on a circuit board with an above-board height of just 0.43 inches (10.9mm), and they exhibit flexibility with N+M fault tolerance for parallel operation.

The 300V Micro Family features Zero-Current Switching/Zero-Voltage Switching (ZCS/ZVS) architecture, which decreases noise and increases reliability and efficiency. The modules also meet safety requirements with test isolation voltages rated at 3000 Vac from input to output, 1500 Vac from input to the baseplate, and 500 Vac from output to the baseplate.

Compliance with specific regulations is demonstrated by the RoHS compliant variants of the product, which can be identified by certain pin options denoted in the part numbering. The summary datasheet also includes a range of operational and storage temperature grades for different configurations. These range from -55°C to +100°C for operating temperatures, -65°C to +125°C for storage temperatures, and provisions are made for handling temperatures during soldering processes.

Part Numbering System & Product Overview

The part numbering system is designed to identify various product configurations, which include differences in output voltage, output power, pin style, and baseplate design. Notably, the output power options vary depending on the output voltage, ranging from 50W to 150W.

Pin styles include options for tin-lead or ModuMate gold in various lengths, and RoHS compliant finishes. Baseplate variations cater to different mounting requirements and are available in slotted or threaded through-hole designs.
