The PFH500F power modules can be connected in parallel using the droop mode current share option to provide additional power. This video shows a graph of how…
- What do PFH500F AC-DC power module evaluation boards provide?
In this video, TDK-Lambda discusses the evaluation boards that are available for the baseplate cooled PFH500F AC-DC power modules. Two boards are available for each output voltage…
- How do non-isolated buck, boost, and buck-boost converters differ?
Non-isolated buck, boost and buck-boost topologies are utilised in the designs of many AC-DC power supplies and non-isolated DC-DC converters. Although many of the patents were filed…
- How to ensure reliable operation of DC-DC converters (cooling and derating)
Today’s manufacturing techniques have improved DC-DC reliability considerably. The use of surface-mount placement for 100% of the components, computerised optical inspection of solder joints, automated test and…
- DC-DC converter printed circuit board and input power considerations
DC-DC converters are relatively easy to use and, with a few precautions, will provide years of reliable operation. Most manufacturers will have instruction or application notes on…
- What external components are required with a DC-DC converter?
Using a standard off-the-shelf DC-DC converter reduces the time, risk and cost associated with developing a discrete version. There are usually, however, some additional external components required…
- What types of applications are most suited for isolated DC-DC converters?
Robots assemble the CC-E series of DC-DC converters Low power DC-DC converters offer a simple way of deriving multiple system voltages from a higher power AC-DC supply.…
