Electrical systems in military vehicles are normally required to meet stringent transient requirements.
RoHS compliant, through-hole full size VI Chips are intended for wave soldering assembly. The information contained in this document defines the processing conditions required for mounting a full size VI Chip to the PCB using wave soldering or hand soldering.
The following discussion shows how to comply with these standards using modular Vicor DC-DC converters to facilitate the design of complex power supplies.
The scope of this technical note includes design considerations as related to 48V distributed power architectures which employ hot swappable, modular power converters.
Some applications employ power modules with greater output current capability than required by the load.
The design of a filter network is generally needed for DC-DC converters to have low electromagnetic interference (EMI) and high input noise rejection.
For applications that require high voltage outputs, multiple converters may be used in a series output configuration to produce a single output voltage that is the sum of all of the converter outputs in the array.
This application note provides soldering process information for PCB mount VIA products including the MFM™, AIM™, PFM™, VIA BCM® VIA DCM™, etc.
In this application note we will consider 24V systems only, primarily because they are more prevalent where high-end equipment is likely to be used, but also because the same circuits – with small modifications – can be used to meet the requirements of the 12V systems.
This document is intended to provide guidance for making high-quality solder connections of RoHS-compliant Vicor power modules to printed circuit boards.
The output of Vicor 2nd Generation DC-DC converter modules can be programmed from 10 to 110% of their nominal output voltage.
This application note applies to all Vicor through-hole ChiP™ devices.
The DC-DC Converter Module (DCM) provides isolation, regulation, fault protection and monitoring in a single module.
Vicor’s VI-200/VI-J00 and Maxi, Mini and Micro family DC-DC converters are voltage regulating devices, but their wide trim range makes it possible to use them as efficient high-power current sources.
An off-line battery charger — using the Unitrode UC3906 battery charger controller chip and a Vicor Maxi, Mini, Micro Series DC-DC converter module — provides design flexibility, small size, and high efficiency.
Not long ago, designing a 1,000W power supply for operation on worldwide AC lines was a task for the most experienced power design engineers.
This document is intended to provide guidance to users of the Vicor Converter housed in Package (ChiP) Technology to physically integrate ChiPs having through-hole leads into higher-level assemblies.
As the modular DC-DC converter industry realizes greater power densities, proper thermal management must be achieved in order to get the most usable power to the load.
The DCM DC-DC Converter Module encapsulates isolation, regulation, thermal management, and fault monitoring in a single module.
VI Chip® PRM® Regulators and VTM® Current Multipliers can be configured in parallel to allow for greater system power capacity.
