Beschreibung
Demonstration circuit 2840A features the LT®8365 in aBoost inverting configuration. It operates with a switchingfrequency of 400kHz and is designed to convert a 9V to 30Vsource to −250V, with 10mA output current.The demo board contains an optional third charge pumpstage for applications requiring higher output voltages.If needed, remove R14 and install optional components.Output voltage sensing connections remain the same.The LT8365 can be used for different topologies withinput voltages up to 60V. However, component selectionin this demo circuit restrict the input voltage to 30V.The demo board contains a selectable jumper, JP1, to aidin the selection of the desired Sync pin mode of operation.The default setting is Burst Mode® operation.This layout is optimized for good EMI performance andsmall solution size. Input and output filters are necessaryfor CISPR 25 Class 5 emissions. Radiated emissions plotsare included in this manual.
