(1) See the applicable package reference drawing for the dimensions and PC board layout.
(2) Standard option specifies 63/37, Sn/Pb pin solder material.
(3) Lead-free (Pb-free) option specifies Sn/Ag pin solder material.
(4) Includes an Auto-Track compatible output, VO Seq, which sequences with the Track control during power up.

(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-kΩ 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.
