Hi team,
My customer is evaluating TPS92513. Customer found the tDELAY depends on IADJ voltage.
They are using 0.01uF for COMP. According to tDELAY calculation in the datasheet, the delay would be 250us (=0.01uF * 0.7V / 28uA).
Their tDELAY measurement result is as follows.
VIADJ = 1.8V : tDELAY = 250us
VIADJ = 0.9V : tDELAY = 2.5ms
Could you check if the 0.7V of the VCOMP threshold or 28uA of the charge current in the equation (10) in the datasheet depends on VIADJ?
If it has a dependency on VIADJ, could you share us the tDELAY calculation including VIADJ dependency?
This delay time will affect the specification of their end equipment. So, I appreciate if you could clarify the VIADJ dependency on tDELAY.
Regards,
Saito
