STMicroelectronics Lighting Controller, 42V, 4.5 V 200 mA 24-Pin QFN

The STMicroelectronics automotive grade LED drivers combining a boost or SEPIC controller and four low-side constant current sinkers, designed to drive strings of high brightness LEDs. The switching converter section provides the supply rail for the LED strings whose value is constantly optimized for maximum efficiency. The boost or SEPIC controller supports the external synchronization and spread spectrum. It can work simultaneously or exclusively in standalone mode (SAM), controlled only by PWMI signal and in bus driven mode (BDM) through an I2C serial interface.

• AEC-Q100 Grade1 qualified
• Supports battery cranking events down to 4 V supply
