SWCS046M –MARCH 2010–REVISED MARCH 2012
RECOMMENDED OPERATING CONDITIONS (continued)
over operating free-air temperature range (unless otherwise noted)
Lists of the recommended operating maximum ratings for the TPS65910 device are given below.
Note1: VCC7 should be connected to the highest supply that is connected to the device VCCx pin. The exception is that
VCC2 and VCC4 can be higher than VCC7.
Note2: VCC2 and VCC4 must be connected together (to the same voltage).
Note3: If VDD3 boost is used, VAUX33 must be set to 2.8 V or higher and enabled before VDD3.
