Hi,
The circuit structure looks ok to me.
The parameter values cannot be determined unless you provide your schematics including power stage and transformer specs detail.
Note, the feedback loop itself cannot eliminate pulse skipping. It requires a minimum…
Part Number: LM5021 Hi,
If i have LM5021 fed by a startup resistor...which obviously cant sustain it...but i also diode-in a 12V bias.....to sustain it...then if i switch off the 12v bias, then does the soft start capacitor get discharged, and stay discharged…
Part Number: LM5021 Hi Team.
Please help to check the following item, there are some questions about the LM5021MM-1, thanks.
1. How long after the overcurrent occurs will the OCP be triggered?
2. Is there a delay time and what is the time?
Regards and…
Part Number: LM5021 Whether the power supply of LM5021 can only be taken from the primary side of the transformer?
Is it possible Vin to take power from the secondary side?
What will happen if the LM5021 takes power from the secondary side?
Part Number: LM5021 We have an application where we would like to disable a flyback converter that uses an LM5021-2 controller using external isolated small signal from microcontroller, and I was wondering is there any way to achive the same. would the…
Part Number: LM5021 My LM5021 based ac to dc converter, which input voltage (100-305)VAC, 50Hz and output voltage 12VDC @ 0.85Amps.
Switching frequency is 123KHz. Power supply is working fine, but conducted emission test as per CISPR 22 class A (Radio disturbance…
Part Number: LM5021 We are using LM5021MM-2 NOPB PWM IC in a flyback circuit.
We are planning to disconnect PIN4 from the following circuit which is a MOSFET gate by using a transistor and a soft signal to turn of the flyback.
We need a clarification…
Part Number: LM5021 Other Parts Discussed in Thread: UCC28742 , LM5023 HI,
The VCC voltage of LM5021 is too low, and the customer needs a voltage of around 12-15V. Are there any similar devices that can be recommended?
Thanks!
