BPsemi BP3236C LED Driver Chip Datasheet
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.

BPsemi BP2833D Non-isolated Buck Offline LED Driver Datasheet
The BP2833D is a non‑isolated buck constant‑current LED driver designed for 85 Vac‑265 Vac offline lighting. It integrates a 500 V power MOSFET, operates in critical conduction mode, and requires very few external components, reducing system size and cost. The device provides ±5 % LED current accuracy and a range of protection functions including LED open/short protection, CS‑resistor short protection, VCC undervoltage protection and thermal regulation.
Typical applications include LED tubes, ceiling lights and bulbs. Key specifications are a DIP‑8 package, operating temperature from –40 °C to 105 °C, output LED currents of 320 mA (72 V) and 360 mA (36 V), and a 500 V MOSFET rating. Recommended PCB layout guidelines emphasize short ground paths, close bypass capacitors and proper placement of the ROVP resistor for reliable operation.
