Part Number: MC33063A Below is a schematic of design I've created using the MC33063A chip. I am have trouble with Q1 (circled in red) when I use a certain part, and I can't quite understand why.
As a little bit on the theory of operation - I am regulating…
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…
Part Number: MC33063A Hi,
Does TI still provide below marking information for MC33063A?
Just want to check below marking is meet TI rule for IQC check materiel.
Thanks!
Jeff
Part Number: MC33063A-Q1 Hi team,
Could you provide the Crossover Frequency for MC33063A-Q1?
My customer have been using this device for production while the initial design did not consider crossover frequency, so they would like to check the value…
Part Number: MC33063A Other Parts Discussed in Thread: MC34063A Hi Team
Nice to link up.
I have a quick question about MC33063A inverting design, is Vin range still 3~40V under inverting voltage output.
Due to under buck inverting output design…
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…
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…
Part Number: MC33063A Hello everyone,
I am working on a design in which I am using two MC33063A chips to generate two independent voltages: +2.5V and -2.5V. To generate the -2.5V, I didn't have any major issues except for an error on my part in sizing…
Part Number: MC33063A Hi,
my question is related to the thread "MC33063A: MC33063ADR Package Thermals".
Can you please supply the requested RthJC for the D-package in this forum.
This would help me a lot.
Thank you and best regards,
