The DNL family has 3 different option codes for TRACK
function.
Option
code
A:
the
characteristic can be achieved when
the output voltage of PS2 follows the
output voltage of PS1 on a volt-to-volt
basis. (Figure 41)
Option code B:
No TRACK function
Option code C:
Implementation of advanced power
tracking techniques is based on connecting the power
good signal or selecting proper value for external
resistor R1 (Figure 40 to Figure 43).

FEATURE DESCRIPTIONS (CON.)
The amount of power delivered by the module is the
voltage at the output terminals multiplied by the output
current. When using the trim feature, the output voltage of
the module can be increased, which at the same output
current would increase the power output of the module.
Care should be taken to ensure that the maximum output
power of the module must not exceed the maximum rated
power (
Vo.set x Io.max
≤
P max)
.
Voltage Margining
Output voltage margining can be implemented in the DNL
modules by connecting a resistor, R
margin-up
, from the Trim
pin to the ground pin for margining-up the output voltage
and by connecting a resistor, R
margin-down
, from the Trim pin
to the output pin for margining-down. Figure 39 shows
the circuit configuration for output voltage margining.
If
unused, leave the trim pin unconnected.
A calculation
tool is available from the evaluation procedure which
computes the values of R
margin-up
and R
margin-down
for a
specific output voltage and margin percentage.

Voltage Tracking
The DNM/DNL family was designed for applications that
have output voltage tracking requirements during
power-up and power-down. The devices have a TRACK
pin to implement three types of tracking method:
sequential, ratio-metric and simultaneous. TRACK
simplifies the task of supply voltage tracking in a power
system by enabling modules to track each other, or any
external voltage, during power-up and power-down.
By connecting multiple modules together, customers can
get multiple modules to track their output voltages to the
voltage applied on the TRACK pin.
