Description

This high-current single LED driver operates from a single cell Li-Ion battery or a 5V input. It uses a sync-buck controller to implement a 4-switch buck-boost topology. This allows it to operate at near 50% duty cycle, with lower component stresses while regulating a constant LED current.
