FEATURE DESCRIPTIONS (CON.
)
Sequential
Sequential start-up (Figure 40) is implemented by
connecting the power good pin of PS1 to the TRACK pin
of PS2 with a resistor–capacitor (RC) circuit. Suggest to
use 1
μ
F ceramic capacitor and 2K
resistor here.
Besides, this configuration requires PS1 to have a power
good function.
PS1
Vin
Ratio-Metric
Ratio–metric is implemented by selecting the resistor
values of the voltage divider on the TRACK pin. To simplify
the tracking design, set initial value of R2 equal to 20K
at
internal circuit and adjust resistor R1 for the different
tracking method. The circuit diagram of Ratio-Metric is the
same as
Simultaneous
when Vo
PS2
tracks the Vo
PS1
.
For Ratio-Metric applications that need the outputs of PS1
and PS2 go to the regulation set point at the same time
(Figure 43), use the following equation (1) to calculate the
value of resistor R1,

V is the maximum difference of voltage between
PS1 and PS2 supply voltage.
For Ratio-Metric applications that need the PS2 supply
voltage rises first at power up and falls second at power
down (Figure 42), use the following equation (2) to
calculate the value of resistor R1,

Simultaneous
Simultaneous tracking (Figure 41) is implemented by
using a voltage divider around the TRACK pin. The
objective is to minimize the voltage difference between
the power supply outputs during power up and down.
For type A (DNX0A0XXXX
A
), the simultaneous tracking
can be accomplished by connecting Vo
PS1
to the TRACK
pin of PS2 where the voltage divider is inside the PS2.
