Name
Description
1, 2, 3
VIN
Input supply — Nominal operating range is from 6V to 20V for the LMZ12010/8/6 and from 6V to
36V for the LMZ13610/8/6.
36V for the LMZ13610/8/6.
4, 5, 6, 7
GND
Power Ground — Electrical path for the power circuits within the module.
8, 9, 10
VOUT
Output Voltage — Regulated 5, 3.3, 2.5 or 1.2V.
A
VIN SENSE +
Positive Kelvin Sense of Input voltage — Tied to VIN pin of the LMZ module.
E
VIN SENSE -
Negative Kelvin Sense of Input voltage — Tied to PGND (EP) of the LMZ module.
L
VOUT SENSE
Positive Kelvin Sense of Output voltage — Tied to Vout banana jack.
+
F
VOUT SENSE
Negative Kelvin Sense of Output voltage — Tied to AGND of the LMZ module.
-
B, D, H
AGND
AGND Ground — Tied to AGND pin of module.
J
NC
No Connect — This pin must remain floating, do not ground.
C
EN
Enable — Input to the precision enable comparator of the LMZ Module.
K
TEMP SENSE
Connected to top of the Rts temperature sensing resistor. Temperature measurements can be
made by measuring the temperature dependant resistance between TEMP SENSE and VIN
SENSE -. Convert the resistance to temperature with the following equation: Temperature (C)
