Totem pole output.
A constant output current of 100 mA or a
peak output current of 1 A can be ob-
tained.
CB:
Bootstrap output.
Connect a bootstrap capacitor between
this pin and the n-channel MOSFET source-
side pin of the switching element when
using a step-down voltage circuit.
Short-circuit this pin and the V
using a step-up voltage circuit.
