LR8421 General Description

Boost and Rectifying Switch Input. Connect an inductor between this pin and VIN. Keep the PCB trace lengths as short and wide as is practical I to reduce EMI and voltage overshoot. If the inductor current falls to zero, or pin CE is low, an internal anti-ringing switch is connected from this pi.
