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.
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 VIN(+).
Thermal Considerations
Introduction
The LC016 power module operates in a variety of ther-
mal environments; however, sufficient cooling should
be provided to help ensure reliable operation of the
unit. Heat-dissipating components inside the unit are
thermally coupled to the case. Heat is removed by con-
duction, convection, and radiation to the surrounding
environment. Proper cooling can be verified by mea-
suring the case temperature. Peak case temperature
8-1265(C).b

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 100
°C. The output power of the module should not exceed
the rated power for the module as listed in the Ordering
Information table.
Heat Transfer Without Heat Sinks
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 3.0 ms–1 (600 ft./min.).
