The BP3236C is a high‑efficiency, TRIAC‑dimmable LED driver chip with integrated 500 V power switch and multiple protection features.
The BP3236C LED driver chip from BPsemi supports TRIAC dimming and operates in critical continuous‑current mode, suitable for Buck, Buck‑Boost and Fly‑back LED power supplies. It integrates a 500 V power MOSFET and uses a patented JFET‑powered architecture that requires minimal external components for excellent constant‑current performance.
The device includes extensive protection functions such as LED open‑circuit, short‑circuit, over‑voltage, undervoltage, and over‑temperature regulation. It is offered in an SOP‑8 package and is intended for applications like LED bulbs, candle‑type LEDs, and other general lighting solutions. This manual is written in Chinese.
