(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 (Pb) – free option specifies Sn/Ag pin solder material.
(4) Includes an Auto-Track compatible output, V_O 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 75 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 SMD package version, do not elevate the module PCB, pins, or internal component temperatures this peak
temperature.
