Part Number: MC34063A Tool/software: During usual production of electronic boards (consolidated ten-years-old design), we had an oscillator and regulation issue at startup of an MC34063A regulator in buck configuration. The circuit has 220uF input cap…
Part Number: MC34063A I ask a question about MC34063 months ago.
MC34063A: there seems to be overcurrent when startup for newly bought item - Power management forum - Power management - TI E2E support forums
But there's no reply and the question…
Part Number: MC34063A Tool/software: Dear TI team,
Please help with the continuous Output current capability of this IC vs Vout range. Also if any related application note or calculation tools is available ??
Dear Feng,
Feng Ji said: Please measure the voltage across R140. That is the two terminals of R140. Connect the probe GND to "+34V
The previously measured waveform shared to you on 5th September 2025 is as per your instructions only. The probe is…
Part Number: MC34063A Other Parts Discussed in Thread: TPS43060 Hello,
I am working on a design for a boost converter and currently using the MC34063A.
Converter requirements:
input voltage +11.5V

Part Number: MC34063A We have been using the MC34063 switching regulator as a step-down converter or step-up converter for years. In one assembly, we are experiencing high inrush currents. These are as high as 800mA for approx. 1s. In this assembly, the…
Part Number: MC34063A Hi
After installation, the output voltage was tested to be negative. When a unit from 2024 was used, the output was normal. Could you please help us check if our application circuit is inappropriate? How should I make adjustments…
Part Number: MC34063A Hi
The customer has a question
1.Are there different L/C in the same reel? (OAETD + OATEN )
2.The test waveforms of normal and abnormal products are as follows
Input 12V; L2 ON period measured about 5usec; TC measurement…
Part Number: MC34063A Tool/software: Hi, i am using MC34063A IC for boost the battery voltage to 12v, 1.5A rating.
my specification is- 12v battery input,
12v output@1.5A current
so please suggest circuit with proper inductor value and feedback…
