Overview
The datasheet presents an overview of the 300V Micro Family DC-DC Converter Modules by VICOR, detailing their size, functionality, and applications. These converters are explicitly designed for a variety of industries and have an actual size of 2.28 x 1.45 x 0.5 inches [57.9 x 36.8 x 12.7mm].
Features & Benefits
The modules offer a DC input range of 180-375V and are capable of withstanding an input surge of 400V for 100ms. They provide a DC output in the range of 3.3-48V, with an adjustable output voltage between 10-110% of the rated value. With regulation at ±0.5% from no load to full load and an efficiency of up to 90%, these converters are efficient and dependable. The converters also boast a high power density of up to 90W per cubic inch and provide low-noise operation through a high-frequency zero-current switching/zero-voltage switching (ZCS/ZVS) architecture.
Applications
The datasheet acknowledges a wide range of applications, including usage in off-line systems with auto-ranging or power factor correction (PFC) front ends. Target industries encompass industrial and process control, distributed power, medical, automatic test equipment (ATE), communications, defense, and aerospace sectors. It is important to note that for proper operation, users should refer to the Design Guide & Applications Manual for Maxi_Mini_Micro Family.
Absolute Maximum Ratings
The module’s maximum ratings include an operating temperature range of -55°C to +100°C and a storage temperature range of -65°C to +125°C. The datasheet specifies isolation voltages and testing conditions for the input/output and baseplate, advising on maximum voltage ratings, such as +IN to ~IN voltage and PR to ~IN voltage, each rated at about -0.5 to +7.0 Vdc for safe operation.
Product Overview
These regulators are parallelable, with N+M fault tolerance and feature an isolation voltage rated at 3000Vrms from input to output. They comply with RoHS standards when the ‘F’ or ‘G’ pin option is selected. An accompanying figure demonstrates the module’s height above the board at 0.43 inches [10.9mm]. The document outlines other mechanical specifications like pin soldering temperatures and mounting torque.
Part Numbering and Product Grade
VICOR also offers a guide to part numbering, which includes information on product type, output voltage, product grade, output power, pin style, and baseplate options. Product images may not reflect the actual current product markings and cosmetic features, as indicated on the datasheet.
Regulatory Compliance
The document emphasizes that the 300V Micro Family DC-DC Converter Modules adhere to RoHS standards, ensuring compliance with environmental and safety regulations.
Note: It’s mentioned that some configurations might not be available, urging the users to check for availability.
The datasheet revision noted is 10.8, and the date of issue is October 2022.
