Chip Rising CRM6112 LED Driver Datasheet

The CRM6112 is a high‑integration DCM (inductor‑current discontinuous mode) LED driver chip that uses primary‑side feedback to maintain constant current without a secondary feedback circuit. It integrates a 600 V power MOSFET, offers ±3 % current accuracy, and includes multiple protection features such as LED short‑circuit, open‑circuit, over‑temperature, over‑voltage, and UVLO.

The device is supplied in an SOP8 package with a pinout that provides FB, VDD, CS, DRAIN and GND connections. Electrical parameters include an input voltage range of 85‑264 VAC, a typical switching frequency of 40 kHz, a maximum power dissipation of 0.5 W, and an operating temperature range of –40 °C to 85 °C. Detailed PCB layout guidelines are provided to minimize interference and ensure reliable operation. This manual is written in Chinese.
