ZHCSU66J August 2001 – December 2023 UCC29002 , UCC39002
PRODUCTION DATA
The UCC29002 device operates in the Normal Running Mode when not starting up, when not faulted, and when not disabled. In Normal Running Mode, the CSO output is connected to the LS Bus Driver and the Adjust amplifier input follows the Error Amplifier output voltage to sink a current at the ADJ pin.
The LS Bus Driver output drives the LS Bus in the system if the CSO voltage is higher than all other CSO voltages in the system. In this case, the UCC29002 assumes the role of load-share leader. If the CSO output is lower than the voltage at the LS pin, the device assumes the role of load-share follower. Depending on system conditions, the UCC29002 device can change roles from leader to follower, or vice-versa, and back again any number of times. Either situation is a normal running condition.
