MC34063: A tough lesson – Matt's Tech Pages
http://www.mattmillman.com/mc34063-a-tough-lesson/
I have been using MC34063 for 20 years, this year I had exactly the same problem where a audio codec failed low ohm and caused the MC34063 to burn out. I have fixed the cause of the codec failing. I usually use electrolytic for …

Post subject: Experiments with the MC34063 and Audio Ckts. Posted: 09 Oct 2018 9:00 pm . Joined: 29 Dec 2010 4:07 am Posts: 353 I recently purchased a board on Ebay that seems to be for Nixie Tubes. It also seems to work very well for Nixie tubes, although I haven't tried anything with it yet. I do know it works for a small amount of DC power ...

MC34063 Description The output switch is an NPN Darlington transistor. The collector of the output transistor is tied to pin 1, and the emitter is tied to pin 2. This allows the designer to use the MC34063 in buck, boost, or inverter configurations. The maximum collector-emitter saturation voltage at 1.5 A (peak) is 1.3 V, and the
My switching power supply (mc34063) makes audible …

The lack of error amplifier (it has just a comparator) and PWM modulator in MC34063 might generate audible subharmonic noise due to erratic switching pattern. Change it to something like LM2675 and your problems will be probably gone You can also get a fixed 3.3 volt version of LM2675 to remove the voltage setting resistors. Regards, Janne Logged

The MC33063A and MC34063A devices are easy-to-use ICs containing all the primary circuitry needed for building simple DC-DC converters. These devices primarily consist of an internal temperature-compensated reference, a comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch.
