Transmitting PWM over a long cable, how to prevent ringing?
I want to transmit three 5V 32kHz PWM signals, with fast rise and fall times (approx. 10ns), over a 2m long, 4 wire telephone cable (RJ11), with one of the middle two wires as common ground. The ...

Two switch forward converter with transient spikes on gate to source voltage
I have a problem with my two switch forward converter.
As soon as the current increases at the input from around 200mA, a transient/spike starts appears at both the turn-on and turn-off of Vgs. The ...

Why is there an output ripple on my LM2576? [duplicate]
I built a buck converter using the LM2576HVT-15/NOPB. I built it exactly like the recommended schematic:
The diode I am using is a 1N5822 and the inductor is a 470uH inductor with a 100uF ...

When does ringing on the switch node of a boost converter become problematic?
I'm working on a 5 V to 15 V boost converter with a low-current output (~5-10 mA). The supply runs in discontinuous mode because this is a small space-constrained circuit with a small inductor.
I did ...

Voltage follower output half wave signal; how can I reduce the ringing on the output?
I have used a voltage follower with a TSH082. I was able to get a half-wave signal with some slight ringing on the output (shown below).
Is there a way to reduce the ringing on the half-wave signal ...

Ringing across IGBT with Infineon driver IC
I am testing the 1ED3123MC12H driver IC with an IKW15N120BH6 IGBT in a buck converter circuit.
Vdc=30V, 0.6mH and Fsw=10 kHz.
Ringing is creating a problem.
How can I fix the ringing?
