  • RE: MC33063A: quiescent current data in inverting buck-boost mode

    Hi Wiky Liao, I hope you have found the source of the leakage in the customer board. I will close this thread for now, as there are no additional comments. If you have further questions or need more help in analyzing the board, feel free to comment below…

  • MC33063A: Having trouble determining values needed for capacitors/resistors/inductor

    Part Number: MC33063A I'm planning on using this to step up a battery voltage from 3.7 to 5v. Looking at the datasheet, the step-up circuit given is much larger from 12-28v. I see the table for determining the values, but I'm not sure what ton and toff…

  • MC33063A-Q1: MC33063A-Q1

    Part Number: MC33063A-Q1 Hi TI support team I intend to use MC33063A-Q1 for 5V 200mA dc/dc regulator for a low orbit satellite circuitry. I assume the MC33063A-Q1 is fabricated with a BJT technology How can I verify that Regards Shaya

  • MC33063A: The 0.33OHM resistor damage issue

    Part Number: MC33063A Hi team Our customer is using MC33063A as step-down regulator(24Vin, 5V 150mA out), and they are using 0.33ohm with 0805 package(0.125W) for Ipk sense. The power consumption should be OK for 0805, but they found that this resistor…
