Hi
Our customer evaluates TPS92641 with TPS92641EVM. And they modified the EVM to test the analog dimming.
IADJ pin : Radj1=10kohm, Radj2=15kohm, VREF pin is opened. And it is connected to the DC supply(3.3V)
CS pin : Rcs=0.33ohm
However the current does not become 0A at 0V. (it is 15mA.)
(0V=0%, 3,3V=100%)
Why does it so? Please give us any advice for this?
Regards,
