Note that low power devices are usually slow speed devices.

Also, what is the function of Q2 in this circuit? The output was as follows. Can anyone tell me why the waveform is lean towards the back? Nov 23, 8, 6, Feb 16, 2.

Posted by Faizan Ahmad in forum: How does this happen? Feb 6, 2. So, let’s take 13 microseconds 0.

Why did you replace an emitter-follower pull up device with a 47K resistor? No, create an account now.


Aug 1, 7, 2, The datasheet says the slew rate is 0. After I modified the circuits, which Q1 was replaced with 47K resistor and I put diode between pin 7 and the base of Q3. LMD Datasheet is attached. Feb 16, 3.

Your name or email address: Feb 16, 1. View attachment Figure 3 flyback circuit provides power input for the circuit in Figure 2 When I measured the pin 7 output at its original circuit in Figure 1, its output is dc voltage around Looking at your o-scope output, my calibrated eye is fairly accurate and the datasheet is exactly right.

View attachment Figure 4 Modified circuit Here is the modified circuit output, which is not my expectation. That means, according to my calibrated eye, the valley is about 25 microsecond wide.

Many of these devices are operated by non-tech-savvy users who may not know how to maintain their own device security.

Yes, my password is: Can anyone tell me what this cable assy is for? Posted by gaya3eeee in forum: You need a slower Pwm frequency or a faster op amp. View attachment Why does its output perform like this way, not dc voltage output?

Feb 18, 4. That means 13 microSeconds going down and 13 microseconds going up. This is a very large increase in output impedance, and introduces a phase shift and low pass filter into the second opamp’s feedback loop.

Quote of the day. I have an original circuits as follows:
