Swimming Upstream! Considerations in Automotive Upstream Point-of-Load Conversion 

著者: Kieran McDonald - 2015-07-08 09:31:50.0

Many automotive power supply architectures require upstream point-of-load (POL) conversion, particularly Advanced/Autonomous Driver Assistance Systems (ADAS) applications where the low core voltage of many System-On-Chips (SoC) and Digital Signal Processors (DSP) are beyond todays Switched Mode Power Supply’s (SMPS) maximum conversion ratio or main switch minimum off-time capability.  POL conversion typically involves down conversion from a primary, battery connected rail voltage to a lower secondary voltage rail required by a particular load.  Other application and load dependent attributes may be required too, such as low noise, high PSRR or high levels of load transient response.  However, adding secondary power supplies upstream of the battery connected primary converter can lead to issues.




Mastering the Art of Sound

Gone are the days of special-ordering a CD or vinyl record at the local music store, and anticipating its delivery for weeks afterwards. Now thanks to cloud-based services like Spotify or SoundClound, we are able to listen to our favorite songs anytime, anywhere.

But, for this convenience, have we sacrificed quality?
