Sequential Start-up

Sequential start-up (Figure 40) is implemented by placing an On/Off control circuit between VoPS1 and the On/Off pin of PS2.

Ratio-Metric

Ratio–metric (Figure 42) is implemented by placing the voltage divider on the TRACK pin that comprises R1 and R2, to create a proportional voltage with VoPS1 to the Track pin of PS2.

For Ratio-Metric applications that need the outputs of PS1 and PS2 reach the regulation set point at the same time.

The following equation can be used to calculate the value of R1 and R2.

The suggested value of R2 is 10kΩ.
