Silergy SA33766
The SA33766 is a dual-channel buck controller designed for automotive LED front lighting systems, including high beams, low beams, daytime running lights, turn signals, fog lights, and static cornering illumination. The SA33766 implements boundary control to generate two separately adjustable constant current outputs simultaneously, ensuring a rapid LED current response and high precision. This design is particularly well-suited for advanced lighting technologies, such as Adaptive Driving Beam (ADB) and flexible lighting effects.| Part No. | SA33766 |

GENERAL DESCRIPTION
The SA33766 supports a wide input voltage range of 4.5V to 60V, accommodating LED voltages up to 53V and LED currents up to 1.6A. The SA33766 incorporates several fault protection features, including thermal warning, thermal shutdown, SPI error detection, short-circuit protection, and opencircuit LED protection. In the event of a communication failure, the chip will automatically switch to limp-home mode to ensure normal system operation.FEATURES
