Description

ACE715C is a step-up converter designed for driving up to 7 series white LED's from a single cell

Lithium Ion battery. 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. Tiny package type

provides the best solution for PCB space saving and total BOM cost.

ACE715C is available in SOT23-6 package that is PB free.
