  • TPS92560: Boost Constant Current getting fried directly after powering up

    Part Number: TPS92560 Hello! I am trying to design a LED replacement board for 12V GY6,35 Halogen lamps. My design uses a Osram Duris S10 LED, which is supposed to be driven with 38 V and a constant current of 100 mA. This is the schematic of the…

  • TPS92560: Component calculator restriction on input voltage

    TI Thinks Resolved
    Part Number: TPS92560 Hi there, In the product page of the TPS92560, there's a component calculator. I want to use it as a boost with current control, but in the component calculator, VIn has to be between 8~16V and my application goes from 10 to 32V…
