    Hi John, Here is an example of current booster design concept that may meet your design requirements. I did not place current limiting and rest of protection circuitry in the simulation. Since OPA462 has the current protection feature, you may design around…

    Part Number: OPA462 Hi Team, A customer supplies 170-180V to OPA462 and the device turns hot. Whenever he reduced the supply voltage the device cools down. Upon checking the quiescent current of the device, it consumes 2mA which translate to 180V x 2mA…
