Part Number: TPS2493
Hi Team,
Would you advise below three questions from the customer?
1. From data sheet P23, is the ton calculated in equation (14) the time to charge
the output capacitor Co to Vcc (max),and is it correct to understand that the time to charge the
TIMER capacitor Ct from 1V to 4V at the same time?
2.Is the time to charge the TIMER capacitor Ct from 1V to 4V from the current limit / power limit detection to the start of
operation (FET turn OFF)?
3.After the limit operation starts, the sequence is to retry when 16 cycles of charge / discharge
to Ct are repeated (P19 Figure 18). The period of 16 cycles is the ratio of ton and charge / discharge
time (1:10 ) Or is Tretry calculated by the formula (26) on page 26 applicable to a period of 16 cycles?
Thanks
Best regards,
Shidara
