    Do you really think it is necessary to get that complicated to power an LED? What kind of LED is this?

    Some LEDs come in 96V 100W ratings

    This driver could work here.
    LPF DC amp to 500kHz current mode PWM to boost regulator out

    Thanks for the reply.
    The driver is used to give output max 18W. 1W LEDs are used. For 18W 18 LEDs, for 15 W 15 LEDs ...
