2 / 28 page UCC29002 UCC29002/1 UCC39002 SLUS495H − SEPTEMBER 2001 − REVISED AUGUST 2007 2 www.ti.com DESCRIPTION (continued) The functionality of the UCC29002/1 differs slightly compared to the UCC39002. The UCC39002 will force the maximum adjustment range at start up to quickly engage load sharing; the UCC29002/1 ADJ amplifier will operate in a linear mode during start up, resulting in a more gradual load sharing at turn on. During transient conditions while adding or removing power supplies, the UCC39002 protects the system by keeping the load share bus disconnected from the remaining supplies. By disabling the adjust function in case a short of the load share bus occurs to either GND or the supply rail, it also provides protection for the system against erroneous output voltage adjustment. The UCC39002 also meets Intel’s SSI (Server System Infrastructure) loadshare specifications of a single-line load share bus and scalable load share voltage for any level of output currents. The UCC39002 family is offered in 8-pin MSOP (DGK), SOIC (D), and PDIP (P) packages. absolute maximum ratings over operating free-air temperature (unless otherwise noted)}w Supply voltage, current limited (VDD) −0.3 V to 15 V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
