Tool/software: WEBENCH® Design Tools
It is about the data sheet items.
In the overload section, does "internal switch current limit threshold" refer to "Isw"?
Isw is the average and not the peak?
There is a considerable difference between min (200 mA) and Typ (400 mA) of "Isw".
For example, in Fig. 4 of the datasheet, Io can take over 100 mA when "Vin = 2.4 V, Vo = 5 V".
Perhaps this is when Isw thinks it is 400 mA.
Il, max = (Vout * Iout) / (0.8 * Vin) + 0.1 = (5 * 0.1) / (0.8 * 2.4) + 0.1 = 0.360416667 A
If you enter "Vin = 2.4V, Vo = 5V, Io = 0.1A" on WEBENCH, "The current limit of the parts has exceeded" is answered.
Perhaps this is when Isw thinks it is 200 mA.
Which is the correct answer?
