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, 3, 5,10,
13,16
GND
Common ground connection for the Vin and
Vout power connections.
2, 4, 6
Vin
The positive input voltage power node to
the module.
7
Inhibit
Applying a low-level ground signal to this
input disables the module’s output.
8
UVLO Prog
Connecting a resistor from this pin to
ground allows the on threshold of the input
undervoltage lockout (UVLO) to be
adjusted higher than the default value.
9, 12 ,15
Vout
The regulated positive power output with
respect to the GND node.
11
+Sense
The sense input allows the regulation
circuit to compensate for voltage drop
between the module and the load. If used,
it should be connected to Vo.
14
-Sense
If used, -Sense should be connected to the
ground return at the load.
17
Vo Adjust
A 0.05 W 1% resistor must be directly
connected between this pin and GND to
set the output voltage.
18
Track
This is an analog control input that enables
the output voltage to follow an external
voltage.
19
Margin Up
When this input is asserted to GND, the
output voltage is increased by 5%.
20
Margin
Down
When this input is asserted to GND, the
output voltage is decreased by 5% from
the nominal.
