SLIS178B October 2017 – January 2018 TPS92830-Q1
Automotive lighting often reuses the same LEDs for different functions with different brightness, for example, daytime running lights (DRL) and position lights, or stop and tail lights. Analog dimming by changing the constant current may affect LED color temperature. PWM dimming could easily achieve the dimming ratio with the same color temperature.
The TPS92830-Q1 device provides a precision PWM generator with a synchronization PWMOUT output. Its integrated high-precision PWM generator ensures homogeneity across different devices.
