TPS92602-Q1: About TPS92602-Q1 CC & CV mode

Part Number: TPS92602-Q1

Hi TI,

For this part, we know both has function CC & CV, how could we know the LED driver set on CV or CC mode?

Does it base on LED device to determine it work on CC or CV mode?

    Hi Johnny,

    It depends on the voltage and current of the LED load. If the circuit reaches the current set-point earlier than the voltage set-point, it works in CC mode. If the circuit reaches the voltage set-point earlier than current set-point, it works in CV mode. The current set-point depends on the RLED_SNS resistor. The voltage set-point depends on the resistor divider at OVFB pin.
