Part Number: LM5025C Tool/software: In some unencrypted Spice models downloaded from the TI website, controlled source combinations were found. As shown in the figure, the input voltage VCCINT is logically judged in the box on the right side of the figure…
Part Number: LM5025C Other Parts Discussed in Thread: LM5025 Hi
There is a problem that the out (pin 9) is short-circuited with the GND during the input on/off test. I want to improve it, so which part should I review?
Thanks
Part Number: LM5025C Other Parts Discussed in Thread: LM5025 Hi everyone,
I make a DCDC Buck converter with this schematic to provide, with input 48V, and exit of 24V.
With the LM5025, the converter starts to supply 24V at an input of 36V. This is why…
Part Number: LM5025C Other Parts Discussed in Thread: LM5025 Dear Expert
Our company used the active embedded chip LM5025 to make a 150W power supply from 110DC to 15V. The customer proposed that the output rise waveform was not monotonous (there were…
Part Number: LM5025C Other Parts Discussed in Thread: LM5025 , The content I posted last time was an idea to solve the unexpected behavior.Today I will provide you with more detailed information.
The phenomenon is that even though the voltage is below the…
Part Number: LM5025C Hi TI:
Why when I use LM5025C CS2 PIN for current limit, the hiccup frequency changed ...
First I short output, then increase input voltage slowly. I found hiccup frequency increased immediately.
C2 is SR mos stress, C3 is SS voltage…
Part Number: LM5025C Other Parts Discussed in Thread: LM5025 , UCC27200 , LM5025B , LM5025A Dear Expert,
We are using LM5025 and UCC27200 together to Active Clump Converter and worry that UCC27200 has been broken when power down state.
We can not find reasons…
Part Number: LM5025C We find another behavior that controller output unstable. when power down state, Case 1 is that Clamp-SW gate(=controller output)
is keeping "High" ( green Plot ), Case 2 is going to "Low". We would like to know what happen.…
Part Number: LM5025C Dear engineering team,
Last week we asked a question re active clamp using LM5025C, then Steve Mappus respond me and seems to be improved. thanks.
Well we would like to confirm that this operation is reasonable or.
Attached is simplified…
Part Number: LM5025C Hi, we are developing Active Clamp 48V DC-DC but unstable, especially worry about broken a gate driver when load is haevy. Attached is simplified primary schematic controller to main transformer, and we began to look at Clamp capacitor…
