Ir2153 1000V floating voltage problem


New member
Pls can someone tell me how to solve the problem my ir2153 smps produce more than 1000V from the output at least that's what multimeter show me and when I connect a led on it nothing light up, I don't understand what kind of voltage is that my Np was 2x15 turns while the Ns was 2x6, at first I use HP laptop charger transformer with the 24V winding and it show the same floating 1000V I use an inductor on a rod and place it then the voltage dropped to 24V and powered a one horse power motor then I remove the transformer and place this my own winding when I place the same inductor no difference I need help urgently please
