Shenzhen Sunmoon Micro SM2396EK

SM2396EK is a high-efficiency dual-channel LED linear constant-current control IC featuring TRIAC detection and line voltage compensation. Using patented constant-current and constant-power control technology, the IC monitors the VT pin voltage to regulate output current, keeping input power essentially constant despite input voltage variations. Simultaneously, it monitors the TRIAC pin voltage to control output current — disabling the TRIAC port when no TRIAC is connected to the system, and enabling it normally when a TRIAC is present.

The IC incorporates an over-temperature regulation function that reduces output current when the chip temperature becomes excessive, improving system reliability.
