As an example let us calculate the worst case maximum load
current at T A = 70 °C. The worst case R DS(on) at 25 °C occurs
at an input voltage of 1.2 V and is equal to 76 m ? . The
R DS(on) at 70 °C can be extrapolated from this data using the
following formula:
R DS(on) (at 70 °C) = R DS(on) (at 25 °C) x (1 + T C x ? T)
Where T C is 4250 ppm/°C. Continuing with the calculation
we have
R DS(on) (at 70 °C) = 76 m ? x (1 + 0.00425 x (70 °C - 25 °C))
= 90.5 m ?
The maximum current limit is then determined by
P (max.)
Recommended Board Layout
For the best performance, all traces should be as short as
possible to minimize the inductance and parasitic effects.
The input and output capacitors should be kept as close
as possible to the input and output pins respectively.
Connecting the central exposed pad to GND, using wide
traces for input, output, and GND help reducing the case to
ambient thermal impedance.
I LOAD (max.) <
R DS ( on)
which in case is 1.9 A. Under the stated input voltage
condition, if the 1.9 A current limit is exceeded the internal die
temperature will rise and eventually, possibly damage the
device.
