Part Number:LM5121
Hello guys,
One of my customers is designing a schematic and BOM using LM5121 for their new products.
For the design, they want to know tRES (Hiccup Mode Off-time). Do you have any equation to calcurate tRES?
I know the total time of tRD and tRES can be calcurated by equation 36 in 8.2.2.14 Restart Capacitor CRES
on page 36 in the device datasheet. But the equation is not for tRES only because it contains tRD.
Could you please give me any equation for tRES only?
Your reply would be much appreciated.
Best regards,
Kazuya Nakai.
