Maxi Family 300V Input DC-DC Converter Module

Category: Electronics, Other Semiconductors, Vicor Corporation

Product Overview

The datasheet presents information on VICOR’s Maxi Family 300V Input DC-DC Converter Modules, designed for high performance in various applications such as off-line systems with auto-ranging or PFC front ends, industrial and process control, distributed power, medical, automated test equipment (ATE), communications, defense, and aerospace. For comprehensive operational details, reference is made to the Design Guide & Applications Manual for the Maxi_Mini_Micro Family.

Features & Benefits

This product line offers advanced power processing through high-frequency Zero-Current Switching (ZCS) / Zero-Voltage Switching (ZVS) which contributes to both high power density and low noise operation. The efficiency of these modules can reach up to 89%, with regulation maintained at +0.3% from no load to full load conditions. The DC input range spans from 180V to 375V and produces isolated DC outputs between 2V to 48V, programmable from 10 to 110% of the specified output. The power density of the module can go up to 100W per cubic inch.

Absolute Maximum Ratings

Absolute Maximum Ratings define the limits on various parameters such as input voltage to output voltage (IN to OUT) isolation which is rated at 3000V, in addition to other isolation parameters of IN to base and OUT to base, listed respectively at 1500V and 500V. The operating temperature range is from -55°C to +100°C while the storage temperature spans from -65°C to +125°C.

Electrical Characteristics

The modules can withstand input surges up to 400V for 100ms, indicating robustness against transient conditions. They also possess a unique low-noise architecture, potentially beneficial in sensitive applications and can be mounted at heights above the board of 0.43in (10.9mm). Sustainability considerations are addressed with RoHS compliance when equipped with the F or G pin option.

Physical and Environmental Details

The Maxi Family modules have a high tolerance for temperature impacts during soldering, with pin soldering temperature withstands specified for both wave and hand soldering. Furthermore, the modules are designed to allow for parallel operation with N+M fault tolerance, thus enhancing reliability. They are engineered for space-saving with actual sizes measured at 4.6 x 2.2 x 0.5 inches (117 x 56 x 12.7 mm).

Part Numbering System

VICOR’s datasheet exemplifies the part numbering system for ordering, identifying output voltage, product grade and temperature ranges, output power, pin style, finish and baseplate options—each denoted by a specific code in the part number. This systematic approach aids in specifying the correct module for different operating conditions and assembly requirements. The datasheet also notes that images may not display current product markings.
