The TCS5201is a step-up converter designed for driving up to 7 series white LEDs from a single cell Lithium Ion battery. The TCS5201uses current mode, fixed frequency architecture to regulate an LED current, which is measured through an external current sense resistor. Its low 200mVfeedback voltage reduces power loss and improves efficiency.

The TCS5201includes under-voltage lockout, limiting and thermal overload protectionpreventing damage in the event of an outputoverload.

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