Response to a Step Load Change from
50% to 75% of IO, max at VI = VI, nom and
TA = 25 °C

Rise Time with Remote On/Off at
VI = VI, nom, IO = 0.8 (IO, max) and TA = 25 °C
Test Congurations
8-489(C).a
Note: Measure input reected-ripple current with a simulated source
impedance (LTEST) of 12 H. Capacitor CS offsets possible
battery impedance. Current is measured at the input of the
module.
