(1)

The converter's internal protection circuitry may cause the output to turn off when the applied input voltage is greater than 60 V.

(2)

When the Track input is fed from an external voltage source, the input current must be limited. A 2.74-k

Ω value series resistor is

recommended.

(3)

During solder reflow of standard SMD package version, do not elevate the module PCB, pins, or internal component temperatures

above a peak of 235°C.

(4)

During solder reflow of Pb - free SMD package version, do not elevate the module PCB, pins, or internal component temperatures

above a peak of 260

°C.
