Notes
1. The minimum input voltage does not include voltage drop in the source supply due to source resistance. It is operating voltage
for static load conditions. To get acceptable load transient performance, the input voltage required will be much higher, in the
7.5 to 8.5 volt range or even higher depending on the severity of dynamic load, source impedance and input and output
capacitance and inductor values. The user should thoroughly test the performance at minimum input voltage using intended
component values and transient loading.
2. Min/Max specifications are guaranteed by design.
