explain
TPS92390 is an automotive type efficient LED driver with boost controller. Four high-precision current wells support automatic adjustment of phase shift according to the number of channels used. Can be passed through I ² The C interface or PWM input controls the LED brightness globally.
The boost controller has adaptive output voltage control based on LED current well margin voltage. This feature can adjust the boost voltage to the lowest level required under all conditions, thus minimizing power consumption. With a wide range of adjustable frequencies, the TPS92390 avoids interference in the AM RF band.
The TPS92390 supports built-in hybrid PWM dimming and analog current dimming to reduce EMI, extend LED life, and improve overall optical efficiency.
