Single IC power management battery maintenance for 48V supplies

Elegant, single-IC power management solutions are readily available for many portable devices, such as smartphones or tablets, which operate at low voltages and low power levels. Power management solutions for high power and high voltage systems, such as those required for many industrial or medical devices, generally require cumbersome, specialised discrete component solutions. In these environments, the LTC4020 simplifies power management by incorporating advanced power management functions into a high voltage and high power single-IC solution.

PCIM provides platform for Rogowski technology demo

PCIM provides platform for Rogowski technology demo
The PCIM exhibition in Nuremberg (May 19-20) provides a platform for Power Electronic Measurements to demonstrate its full range of Rogowski technology based wide-bandwidth current probes. Featuring the latest CWT MiniHF, the company will show how this AC probe provides better common mode immunity to local high voltage transients, and provides a more precise measurement delay which can be compensated for to give improved power loss measurement in power semiconductors using SiC and GaN technology.
