ChipLink CL1570 Non-Isolated Buck LED Constant Current Driver Datasheet

The CL1570 is a non‑isolated linear LED constant‑current driver chip that provides high‑precision current control without a transformer. Output current is set by an external sense resistor and the device includes over‑temperature regulation for reliable operation.

Typical applications include LED ceiling lights, LED bulbs, T5/T8 LED tube lights and other LED lighting fixtures. The chip is offered in TO‑252‑2L, ESOP8 and SOT‑89‑3L packages and can be directly soldered onto aluminum substrates. This manual is written in Chinese.
