Feature Descriptions
Output Voltage Adjustment (Optional on
Single-Output Units)
Output voltage set-point adjustment allows the user to
increase or decrease the output voltage set point of a
module. This is accomplished by connecting an exter-
nal resistor between the TRIM pin and either the V
or V
TRIM and V
point (V
equation determines the required external resistor
value to obtain an output voltage change from V
to V
where R

The combination of the output voltage adjustment
and the output voltage tolerance cannot exceed 110%
(125% for the D) of the nominal output voltage between
the V
Figure 40. Circuit Configuration to Increase Output
The L-Series power modules have a fixed current-limit
set point. Therefore, as the output voltage is adjusted
down, the available output power is reduced. In addi-
tion, the minimum output current is a function of the
output voltage. As the output voltage is adjusted down,
the minimum required output current can increase
(i.e., minimum power is constant).
Synchronization (Optional)
With external circuitry, the unit is capable of synchroni-
zation from an independent time base with a switching
rate of 256 kHz. Other frequencies may be available;
please consult the factory for application guidelines
and/or a description of the external circuit needed to
use this feature.
