For example, the PS1 Voset,PS1=5V, the PS2 Voset,PS2=3.3V, R1 is calculated as follows:

R1 =

[(3.3 − 1.3) − 1.32]

* 20K = 10.303K Ω

Simultaneous Implementation

Similar to the ratio-metric implementation, simultaneous tracking is implemented using a voltage divider on the TRACK pin. The objective is to minimize the voltage difference between the power supply outputs during power up and down. The waveforms of power up and down are showed in Figures 13 and 14.

For type A (DNXXX0A0XXXX A), the simultaneous tracking can be accomplished by connecting VoPS1 of PS1 to the TRACK pin of PS2. Figure 11 shows the circuit diagram of voltage Simultaneous start-up when VoPS2 tracks VoPS1 (only for type A).
