Hi expert
we have two question:
Hi Meng,
1A) The equation is based on the internal circuit design. Is your circuit result not matching with the equation ?
2A) please share calculated values for your design and actual test result. How much % error you have observed ?
Best Regards,
Rakesh
1):I just interested in how to got 11.9. our design is matched.
2): in our understood, R1C1 can reduce inrush current because their increase miler clamp so in the customer test, their got the MOS Qg though test turn on time. then they got the Irush but this value have 30% error with datasheet inrush current equation.
Hi Meng,
1A) 11.9 factor is coming from the internal current sense amplifier
2A) Can you please share the R1C1 values used in the customer design, the MOSFET part number and the inrush current profile with 400uF load.
Is the inrush current profile/value not matching with the R1C1 calculations in the datasheet ?
Best Regards
Rakesh
