Part Number: LM5021 Hi
One of my customer is facing issue with EMI. they have designed 12V/0.85A SMPS based on LM5021. We have done multiple experiment but not able to see major improvement. My customer will share all the test results, schematic & layout…
Part Number: LM5021 in datasheet for the selection of R22, i want to understand whole calculation for how it will give 67 nSec time constant.
Thanks in advance.
Part Number: LM5021 in the datasheet, as per application design parameter requirements mentioned in the datasheet example for selecting inductance of transformer there is some formulas.
In that can someone explain how primary to secondary ratio is calculated…
Part Number: LM5021 Other Parts Discussed in Thread: UCC28C42 Hi experts,
My customer is designing a DC/DC module product based on LM5021. For some reason they must use this part though it is not fully meet the application condition. To make the device…
Part Number: LM5021 Other Parts Discussed in Thread: PMP20809 Hi Team,
Good day. I am posting this inquiry on behalf of our customer.
"I am interested in this reference design: PMP20809 and have a question about it.
It is designed for AC input voltage…
Part Number: LM5021 Hi,
I have three questions, because my customer wants to estimate current of VIN on LM5021 during operating VCC regulator.
*1. IVIN parameter (Typ 2.5mA, MAX 3.75mA) is current with operating VCC regulator before staring operation. …
Part Number: LM5021 hi,
When the customer uses LM5021, the output current increases, the CS pin output exceeds 0.5V, and the chip output low voltage. Why is the output voltage not 0? Is it because of periodic current limitation? If yes, what is the limit…
Hello Darren,
I am just following up. Did this resolve your issue? If it did could you please select resolved at the end of thread?
