Switch Pin 2. Connect an inductor between this pin and V
trace lengths as short and wide as is practical to reduce EMI and voltage
overshoot. If the inductor current falls to zero, or pin EN is low, an internal
100Ω anti-ringing switch is connected from this pin to V
Note: An optional Schottky diode can be connected between this pin and
V
Power Ground
