Working Principle

The TPS92411PDBVR is a DC-DC switching converter that provides a regulated current source to the LED strings. It takes an input DC voltage and converts it into the desired output current and voltage.In operation, the device is enabled by an enable pin, and when this pin is set to \'high\', the following operations begins:1. The internal oscillator starts and provides a clock for the driver circuitry. 2. The driver switches the internal MOSFETs, depending on the voltage and current setpoints.3. This generates a pulse-width modulation (PWM) signal which is then used to regulate the current and output voltage of the LED string.4. The output voltage is then regulated to a precise level, ensuring a constant and reliable level of brightness and current to the LED strings.
