Ratio-Metric Implementation

Ratio–metric is implemented by the selection of the resistor values of the voltage divider on the TRACK pin. Resistors R1 and R2, in Figure 6 determine the tracking method that is implemented.

To simplify the tracking design, R2 initial set value equal 20KΩ at internal circuit and only set one resistor R1 for different tracking method. Figure 6 shows the circuit diagram of Ratio- Metric start-up when VoPS2 tracks the VoPS1.
