Simultaneous

Simultaneous tracking (Figure 41) is implemented by using the TRACK pin. The objective is to minimize the voltage difference between the power supply outputs during power up and down.

The simultaneous tracking can be accomplished by connecting VoPS1 to the TRACK pin of PS2. Please note the voltage apply to TRACK pin needs to always higher than the VoPS2 set point voltage.
