  • RE: TPS55340: TPS55340 to achieve multiple rail outputs with SEPIC?

    For the Sepic converter, the voltage on the internal FET, the SW pin, is equal to the sum of the input voltage and the output voltage. As 36Vin +12Vo=48V>38V, so it is not fit to use TPS55340 in this applicaiton. Sugggest them use a boost controller in…
