AN904 APPLICATION NOTE MAGNETIC AMPLIFIER WITH LPR30 CONTROLLER
by F. Lentini & T. Sampieri
Proper regulation is important in multiple output power supplies where the individual outputs must be tightly controlled. The continuing need for more compact and reliable switching power supplies has aroused renewed interest in a well founded control technique: THE MAGNETIC AMPLIFIER. THE MAGNETIC AMPLIFIER ( shortly written MAG -AMP ), means higher density, simpler control circuit and higher running frequency in Switching Power Supply. The MAG AMP is suitable for controlling individual outputs ranging from a few watts to over 100 watts in power converters whose frequencies range from 20KHz to several hundred KHz.
