Positive remote sense
Positive output voltage
Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
Workmanship: Meets or exceeds IPC-A610 Class II
Notes:
1)
SENSE(–) should be connected to Vout(–) either remotely or
at the converter.
9)
10) Recommended pin length is 0.03” (0.76mm) greater than the PCB
thickness.
11) A thermal interface material is required to assure proper heat
transfer from the flanged baseplate to the cooling surface. Thermal
grease, conductive pads, compounds, and other similar products are
available from many heatsink manufacturers.
2)
3)
Leave TRIM pin open for nominal output voltage.
SENSE(+) should be connected to Vout(+) either remotely or
at the converter.
