Hi. I have a question about the MC33063A converter. We are using R2 = 18K and R1 = 11K, with a desired Vout of 3.3V; however, we are getting 3.59V when Vin is 24V. The capacitance…
Part Number: MC33063A-Q1 Hi team,
Here is the circuit I am using,
When I turned it on R73 was burning. If I reduce the value to 250mohm IC is burning up. And when I connected 1ohm I got 1.2V as output.
What might be the problem? Is the inductor I selected…
Hi Haroon,
Just for double check, oscillator frequency in the datasheet is the crossover frequency of MC33063A-Q1 ?
Customer mentioned Fco should be specified for this device, so please confirm if it's correct.
Part Number: MC33063A Tool/software: Some questions are as follows: 1. How is the output current derived in a boost circuit? 2. Are Q1 and Q2 in the step-down circuit a composite Darlington structure? 3. May I ask if the input voltage of a similar driving…
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

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…
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…
