General Description
The RY3730 is a step-up converter designed for driving up to 8 Series white LED's from a single cell Lithium Ion
battery. The device features integrated overvoltage protection and Its low 250mV feedback voltage reduces power
loss and improves efficiency.
Optimized operation frequency can meet the requirement of small LC filters value and low operation current with
high efficiency. Internal soft start function can reduce the inrush current. SOT23-6 package type provides the best
solution for PCB space saving and total BOM cost.
