Feature Descriptions (continued)
Output Voltage Adjustment (continued)
The combination of the output voltage adjustment and
sense range and the output voltage given in the Fea-
ture Specifications table cannot exceed 110% of the
nominal output voltage between the VO(+) and VO(–)
terminals.
The modules have fixed current-limit set points. There-
fore, as the output voltage is adjusted down, the avail-
able output power is reduced. In addition, 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.
Output Overvoltage Protection
The output overvoltage clamp consists of control cir-
cuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. The con-
trol loop of the protection circuit has a higher voltage
set point than the primary loop (see Feature Specifica-
tions table). In a fault condition, the overvoltage clamp
ensures that the output voltage does not exceed VO,
clamp, max
. This provides a redundant voltage-control that
reduces the risk of output overvoltage.
Synchronization (Optional)
The unit is capable of external synchronization from an
independent time base with a switching rate of
256 kHz. The amplitude of the synchronizing pulse
train is TTL compatible and the duty cycle ranges
between 40% and 60%. Synchronization is referenced
to VI(+).
Thermal Considerations
Introduction
The LW016 Dual-Output-Series power module oper-
ates in a variety of thermal environments; however,
sufficient cooling should be provided to help ensure
reliable operation of the unit. Heat-dissipating compo-
nents inside the unit are thermally coupled to the case.
Heat is removed by conduction, convection, and radia-
tion to the surrounding environment. Proper cooling
can be verified by measuring the case temperature.
Peak case temperature (TC) occurs at the position indi-
cated in Figure 11.
8-1265(C).d

Figure 11. Case Temperature Measurement
Location
Note that the view in Figure 11 is of the metal surface of
the module—the pin locations shown are for reference.
The temperature at this location should not exceed the
maximum case temperature (100 °C). The output
power of the module should not exceed the rated
power for the module as listed in the Ordering Informa-
tion table.
Heat Transfer
Increasing airflow over the module enhances the heat
transfer via convection. Figure 12 shows the maximum
power that can be dissipated by the module without
exceeding the maximum case temperature versus local
ambient temperature (TA) for natural convection
through 2.0 ms–1 (400 ft./min.).
Note that the natural convection condition was mea-
sured at 0.05 ms–1 (10 ft./min.) to 0.1 ms–1 (20 ft./min.);
however, systems in which these power modules may
be used typically generate natural convection airflow
rates of 0.3 ms–1 (60 ft./min.) due to other heat-dissi-
pating components in the system. Use of Figure 12 is
shown in the following example.
