Part Number: TL2845 Hi,
in TL2845 datasheet, we have "Operating free-air temperature" in recommended operating conditions.
And we have "Virtual junction temperature" in absolute maximum ratings.
My customer would like to know if it…
Part Number: TL2845 Hi team,
My customer use PD controller +TL2845 in POE power supply, and use TL2845 as flyback,
I want to know if TL2845 can be used as primary side feedback for isolated power?
or do you have some reference design of isolated and non…
Part Number: TL2845B Other Parts Discussed in Thread: TL2845 , Hi, team,
I just need to confirm one thing with you.
What is the difference between TL2845B and TL2845? I did not find some difference from datasheet.
Thanks.
Johnny
Part Number: TL2845 Dear team,
Customer found in their test that the delay time to output is nearly 600ns which is above 300ns listed in datasheet. Please check the test waveform, the yellow one is the current waveform.
Thanks.
Best regards,
Sammi
Part Number: TL2845 Hello,
We’re seeing the PWM switching frequency increase by 2x at no-load / light-load in a flyback topology. Is this expected behavior?
There is a comment in the datasheet discussing TLx844 and TLx845 output frequency is one…
Hi Prakash,
A frequency of 340 kHz with those components is unusual. Can you double check the values of the components or swap out with a different device to see if this frequency is still occurring? A schematic would also be helpful.

Part Number: TL2845B Other Parts Discussed in Thread: TL2845 Dear all,
I am using TL2845BDR-8 controller to develop DC DC converter for the following specifications.
Vin = 110 V (80 V to 140 V),
Vo = 24 V,
Io = 2 A,
Fsw = 100 kHz,
Fly-back topology,
I found…

We can find the calculate way when RT>5k,but I can't find the calculate way when RT≤5k
Could you help to tell us how to calculate the frequency when RT≤5K。
