Thermal Consideration
General
The regulators are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependant on the airflow
across the regulator. Increased airflow enhances the cooling
of the regulator.
The typical Output Current Derating graph can be found in the
Output section for each model provides the available output
current vs. ambient air temperature and air velocity at V
V.
The product is tested on a 100 x 100 mm double-sided PCB
with 2 oz. copper and the direction of airfow fro pin 10 to pin
22. For surface mount packages, multiple vias must be
utilized.
Definition of product operating temperature
The product operating temperatures is used to monitor the
temperature of the product, and proper thermal conditions can
be verified by measuring the temperature at positions P1, P2,
and P3. The temperature at these positions (T
should not exceed the maximum temperatures in the table
below. The number of measurement points may vary with
different thermal design and topology. Temperatures above
maximum T
allowed and may cause permanent damage.

Function
When two modules are
connected together to share
load current one must be
configured as the MASTER
and the other as the SLAVE.
This pin is used to configure
the module as either
MASTER or SLAVE. To
configure the module as the
MASTER, connect this pin to
GND. To condigure the
module as the SLAVE,
connect this pin to V
When not sharing current,
this pin should be connected
to GND.
This pin is used when
connecting two modules
together to share load
current. When two modules
are sharing the current the
Share pin of both modules
must be connected together.
When not sharing current,
this pin MUST be left open
(floating).
This pin is used when
connecting two modules
together to share load
current. When two modules
are sharing current the Comp
pin of bothe modules must be
connected together. When
not sharing current, this pin
MUST be left open (floating).
