Part Number: MC34063A Hi,
I am using MC34063A in voltage inverter mode as per datasheet which converts +5V to -12V. Now I want to use same for +24V to -15V with >=500mA current, using general purpose transistor like TIP42C or BD140 with MC34063A. Suggest…
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 In January 2026, we had to make circuit adjustments to limit the inrush current. I discussed this with Brigitte. The circuit modification also worked as intended with regard to the inrush current. Since then, we have observed an…

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…
