Beschreibung

KI-Übersetzung

The TPS92390 is an automotive-class high-efficiency LED driver with a boost controller. Four high-precision current sinks support automatic phase-shift adjustment based on the number of channels in use. The LED brightness can be globally controlled via the I²C interface or PWM input. The boost controller features adaptive output voltage control based on the headroom voltage of the LED current sinks. This feature can regulate the boost voltage to the lowest level that meets the requirements under all conditions, thereby minimizing power consumption. With a wide-range adjustable frequency, the TPS92390 can avoid interference in the amplitude modulation (AM) radio frequency band. The TPS92390 supports built-in hybrid PWM dimming and analog current dimming, which can reduce EMI, extend the LED lifespan, and improve the overall optical efficiency. It also has multiple fault diagnostic functions.
