Part Number: LM5022 Other Parts Discussed in Thread: OPA2992 , OPA455 Tool/software: Good day,
I have built a 20VDC - 40VDC converter following the design guidelines from the datasheet. It is producing 40V as expected with no load.
However, its voltage…
Part Number: LM5022 Other Parts Discussed in Thread: CSD19534Q5A Tool/software: HI,Team.
Currently, an isolated flyback power supply is constructed using LM5022, with an input voltage of 10.8 to 31.2V and an output voltage of 12V at 2A. The CSD19534Q5A…
Hi Nicolas,
Export failure issue is fixed, all export options are working fine on production.
Clear your browser cache and try exporting, it should work.
Kindly let us know if there are any further queries.
Thank You

Hello Harry,
How the higher Rsense impact the loop compensation? Will it lower down the bandwidth and phase margin?
As for isolated flyback with LM5022, is there any other controller can be used to replace LM5022 with latch off after OCP? Prefer lower…
Part Number: LM5022 Hi Experts,
When a very short and high current pulse occurs on flyback output, noticed the 12Vout has a dip and then the operation mode change from DCM to CCM for a few cycles to recover.
Is the operation mode change expected?
During…
Part Number: LM5022 Other Parts Discussed in Thread: LM5122 , LM5155 , LM5157 Hi there,
For LM5022 flyback design, the input voltage may drop to 6V for ~20seconds in our application.
Can LM5022 operates at 6Vin for 20seconds?
Thanks

Hi TI experts,
For LM5022 based flyback design, we measured there is about 20ms delay from Input ramps up to Vout starts ramping.
Can i know why there is a delay?
How can we reduce the delay?
Thanks.
