Part Number: LM5021 Tool/software: Hi Sir,
Nice to write the question again!
I'm doing the design for Switching power supply (flyback) from POE, the target of output power is ~60W (26V, ~2.3A).
TPS2372-3 is going to be POE PD interface. And LM5021…
Part Number: LM5021 Tool/software: Hi team,
My customer is using LM5021 in their project and wants to know the MAX voltage of VCC pin. Customer is using this device with an external power suplly at arround 14V. What is the voltage level of this external…
Part Number: LM5021 Tool/software: Hello,
I am looking for a way to deactivate the hiccup mode of the LM5021.
To do this, I removed the soft start capacitor and connected a 200k resistor between VCC pin and SS pin. This disables both the soft start…
Part Number: LM5021 Hello Dear,
We have an application where we developed a power supply using LM5021. Its input voltage range is 90 VDC to 280 VDC and output is 13VDC.
Power supply is designed for 20W. In our application we do not need the skip…
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…
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…
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…
