hello,
Our customer pointed out the output overcurrent taget 32A in TPS53219A Tabe 3 is not cauluated from the 86.6k-ohm RTRIP in Figure 18.
I have calculated the overcurrent tagtet from Figure 18 design example and equation (7) ,then
Iovercurrent=86.6k x 10u / (8 x 1.1m) + (12-1.2)x1.2/(2x0.44ux12x500k)=100A >> 32A.
could you kindly check RTRIP value to closer to the target.
thanks.
