• Manufacturer Part Number: DNL10S0A0S16NFD
• Description: Delphi Dnl, Non-isolated Point Of Load Dc/dc Power Modules 8.3-14vin, 0.75-5.0v/16a Out
• Manufacturer: Delta Electronics, Inc.

FEATURE DESCRIPTIONS (CON.
The output voltage tracking feature (Figure 27 to Figure
29) is achieved according to the different external
connections. If the tracking feature is not used, the
TRACK pin of the module can be left unconnected or tied
to Vin.
For proper voltage tracking, input voltage of the tracking
power module must be applied in advance, and the
remote on/off pin has to be in turn-on status. (Negative
logic: Tied to GND or unconnected. Positive logic: Tied to
Vin or unconnected)

Sequential Start-up
Sequential start-up (Figure 27) is implemented by placing
an On/Off control circuit between Vo
of PS2.
Simultaneous
Simultaneous tracking (Figure 28) is implemented by
using the TRACK pin. The objective is to minimize the
voltage difference between the power supply outputs
during power up and down.
The simultaneous tracking can be accomplished by
