Thermal Consideration continued
Definition of reference temperature (Tref)
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum Tref are
not allowed and may cause degradation or permanent
damage to the product. Tref is also used to define the
temperature range for normal operating conditions.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the module.

Pin
Designation
Function
1
GND
Common ground connection
for the V
in and Vout power
connections.
2
V
in
The positive input voltage
power node to the module.
3
Inhibit
Applying a low-level ground
signal to this input disables
the module’s output.
4
V
o Adjust
A 0.1 W 1% resistor must be
directly connected between
this pin and pin 7(GND) to set
the output voltage.
5
V
o Sense
The sense input allows the
regulation circuit to
compensate for voltage drop
between the module and the
load.
6
V
out
The regulated positive power
output with respect to the
GND node.
7
GND
Common ground connection
for the V
in and Vout power
connections.
8
Track
This is an analog control
input that enables the output
voltage to follow an external
voltage.
9
Margin Down
When this input is asserted to
GND, the output voltage is
decreased by 5% from the
nominal.
10
Margin Up
When this input is asserted to
GND, the output voltage is
increased by 5%.
