Ok, I finally found the equations. All my calculations say that the
switching power is negliable compared to the power dissipated by R_ON. (Only
at high frequencies does it start becoming significant)
P = I^2*R + 2*a*V*I*t*F
which can be rewritten as
P = I^2*R + 2*a*V*Q*F
and a depends on the load type(1/2 for inductive and 1/6 for resistive)
So infact for my case I need only like 200mA to switch the load fast enough
for 50khz(so like 99% of the square waveform is constant).
