The TPS549B22 allows up to 16 different chip addresses for PMBus communication with the first 3 bits fixed as 001. The address selection process is defined by resistor divider ratio from BP pin to ADDR pin, and the address detection circuit starts to work only after the initial power up when VDD has risen above the UVLO threshold. Table 6-4 lists all combinations of the address selections. The 1% or better tolerance resistors with typical temperature coefficient of ±100ppm/°C are recommended.
ADDR pin-strap configuration also programs the light load conduction mode.
