Page 4 of the LT3692 datasheet states that the current from the boost circuit to each of the high side BJT drives is 55mA.
Do you know what current the low side BJTs draw?

Also, page 2 of the LT3692 datasheet also says that Theta (JA) is 35degC/Watt….but do you know what conditions this applies to…eg x cm^2 of thermal copper on back of pcb connected with thermal vias etc etc?
