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…
Hi Jeno,
Sorry for the delay, it is hard to give feedback on your schematics, as long as you are following the equations from the datasheet as shown below it should be fine. Although I must say having a transformer at the output would make things complicated…
Part Number: MC33063A Hi
I have a question: The picture below is the circuit in Spec.
1. Does this circuit use a switching frequency of KHz? ?
2 . For the CT mounted on Pin3-4, what is the basis for selecting 1500pF?
3. Formula table in Spec: What is…
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…
Hello Zheng,
It is not possible to specify the cross-over frequency for the device itself. As Haroon had initially indicated, it depends on external components. The cross-over frequency equals to the bandwidth with which the system can follow a transient…
Part Number: MC33063A Hi,
I just want to confirm if I can use MC33063 for the conversion, Vin = 12V, Vout = -30V, 600mA. If not can you suggest any better devices.
Thanks,

Part Number: MC33063A Dear team,
when my customer used MC33063 for 24Vin and 5Vout. When mosfet turning on, CT output will appear non-linear rising. And the ripple is much higher. Green channel is SW , yellow waveform is CT on 3rd pin.
Do you have any…
Part Number: MC33063A Hi TI Support Team,
I am using MC33063 to step down ~13.5V battery voltage (Power Source/Vboard is 14.4V 2.2Ah Lead Acid Battery) to 5V. I am using 5V output to power 5 relay driver circuit. The MCU I am using to trigger transistors…
