Demonstration board description
Regulation of the output voltage is performed by secondary feedback on the 24 V output.
The feedback network consists of a programmable voltage reference, TSM1011, driving an
optocoupler which ensures the required insulation between the primary and secondary
sections. The optotransistor drives the feedback pin (RFMIN) which controls the operation of
the IC.
The resonant transformer is based on a two-slot coil former and an EER39-PC40 ferrite
core, manufactured by TDK. The transformer ensures safety insulation in accordance with
EN60950.
