Automotive high-side dimming rear light reference design
Description
This reference design is for automotive high-side dimming rear light: which uses BCM to supply the rear light. In the design: the high-side driver TPS1H100-Q1 is used to output PWM supply with different duty cycle. Linear LED drivers TPS92630-Q1 and TPS92638-Q1 are used to drive LEDs in constant current.
Features
