GENERAL DESCRIPTION

The TCS5526 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.
