Feature Descriptions (continued)
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 VO(+)
or VO(–) pins. With an external resistor between the
TRIM and VO(+) pins (Radj-down), the output voltage set
equation determines the required external resistor
value to obtain an output voltage change from VO, nom to
VO, adj:
where Radj-down is the resistance value connected
between TRIM and VO(+), and G, H, and L are dened
in the following table.

Figure 39. Circuit Conguration to Decrease
Output Voltage
With an external resistor connected between the TRIM
and VO(–) pins (Radj-up), the output voltage set point
tion determines the required external resistor value to
obtain an output voltage from VO, nom to VO, adj:
where Radj-up is the resistance value connected
between TRIM and VO (–), and the values of G, H, K,
and L are shown in the following table:
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 VO(+) and VO(–) terminals.

Figure 40. Circuit Conguration to Increase Output
Voltage
The L-Series power modules have a xed 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.
