The load-share bus receiver amplifier is a unity-gain buffer that monitors the voltage on the LS bus. The primary purpose of this amplifier is to ensure that the LS bus is not loaded by internal impedances (other than the 100kΩ) of the UCC29002 device. The LS bus receiver amplifier is internally compensated and has a 15kHz filter on its non-inverting input. To maintain stability, avoid adding significant external capacitance to the LS pin.
