TCS5526
High Performance,Constant Current LED Driver wiht PWM Brightness Control
产品描述
The 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.
