  • MC33063A-Q1: External P-Chan FET switch for more current! Inductor Current?

    TI Thinks Resolved
    Part Number: MC33063A-Q1 Other Parts Discussed in Thread: MC33063A , ALLIGATOR Support, I'm using an external P-chan FET for higher supply current. I worked through the formulas to determine my minimum inductance and output capacitance needed for my application…

  • MC33063A-Q1: Using an External P-Chan FET for more Current, inductor current question!

    Part Number: MC33063A-Q1 Support, I think I may still be having issues with my supply! VOUT on the schematic is actually the +24V input. VFAN is +16V output to a fan. My Ct is currently 2200pF. My inductor current doesn't consistently go back to 0, as…

  • MC33063A: Change inductor value for MC33063A

    TI Thinks Resolved
    Part Number: MC33063A Hi team, Our customer would like to change the inductor value for their design with MC33063A. Please confirm if it is okay to change 220uH value to 110uH or 330uH in the Switch Emitter pin as they don't have available 220uH inductor…

  • MC33063A-Q1: Reverse polarity protection circuit - TVS location

    TI Thinks Resolved
    Part Number: MC33063A-Q1 Is it suggested to put bi-dir TVS before reverse polarity protection PFET or after? (between DG or SG ?)

  • MC33063A: Maximum frequency MC33063ADR

    Part Number: MC33063A Hi Team, Confirming this for our customer: The customer applies power (5V) to pins 6, 7, and ground pins 2, 4, 5, between pin 3 and ground we connect a 1nF capacitor. At pin 3, they have a frequency of 52 kHz, (in datasheet 42 kHz…

  • MC33063A-Q1: Output current at 5V to 12V

    TI Thinks Resolved
    Part Number: MC33063A-Q1 Other Parts Discussed in Thread: TLV61048 Hi Team, We have a customer who wants to use MC33063A-Q1 to step up the voltage from 5V to 12V at 0.5A output current. Can this device output 0.5A from a 5V input to 12V output? What would…
