Description
The CC030-Series Power Modules are dc-dc converters that operate over an input voltage range of 18 Vdc to
36 Vdc and provide precisely regulated outputs. The outputs are isolated from the inputs, allowing versatile
polarity configurations and grounding connections. The modules hav e maxim um pow er ratings of 30 W at a typ-
ical full-load efficiency of 81%.
The power modules feature remote on/off, output sense (both negative and positive leads), and output voltage
adjustment from 90% to 110% of the nominal output voltage. For diskdrive applications, the CC030B Power
Module provides a motor-start surge current of 3 A. The modules are PC board-mountab le and encapsulated in
metal cases. The modules are rated to full load at 100 °C case temperature.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Electrical Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions.
Table 1. Input Specifications
Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-
ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The
safety agencies require a normal-blow fuse with a maximum rating of 5 A in series with the input (see Safety Con-
siderations section). Based on the information provided in this data sheet on inrush energy and maximum dc input
current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further
information.

Data Sheet CC030-Series Power Modules; dc-dc Converters:
January 2000 18 Vdc to 36 Vdc Inputs, 30 W
Design Considerations (continued)
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Source inductance greater
than 12 µH can aff ect the stability of the pow er module.
A 33 µF electrolytic capacitor (ESR < 0.7 Ω at 100 kHz)
mounted close to the power module helps ensure sta-
bility of the unit. For other highly inductive source
impedances, consult the factory for further application
guidelines. (See Figure 14.)
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standard,
i.e.,
UL
1950,
CSA
C22.2 No. 950-95, and
VDE
0805
(EN60950, IEC950).
For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the
input must meet SELV requirements.
The pow er module has e xtr a-low voltage (ELV) outputs
when all inputs are ELV.
The input to these units is to be provided with a maxi-
mum 5 A normal-blow fuse in the ungrounded lead.
Feature Descriptions
Overcurrent Protection
To provide protection in a fault (output overload) condi-
tion, the unit is equipped with internal current-limiting
circuitry and can endure current limiting for an unlim-
ited duration. At the point of current-limit inception, the
unit shifts from voltage control to current control. If the
output voltage is pulled very low during a severe fault,
the current-limit circuit can e xhibit either foldback or tai-
lout characteristics (output-current decrease or
increase). The unit operates normally once the output
current is brought back into its specified range.
Remote On/Off
To turn the power module on and off, the user must
supply a switch to control the voltage between the
on/off terminal and the VI(–) terminal (Von/off). The
switch can be an open collector or equivalent (see
Figure 16). A logic low is Von/off = –0.7 V to 1.2 V, during
which the module is off. The maximum Ion/off during a
logic low is 1 mA. The switch should maintain a logic-
low voltage while sinking 1 mA.
During a logic high, the maximum Von/off generated by
the power module is 6 V. The maximum allowable leak-
age current of the switch at Von/off = 6 V is 50 µA.
The module has internal capacitance to reduce noise
at the ON/OFF pin. Additional capacitance is not gen-
erally needed and may degrade the start-up character-
istics of the module.
8-720(C).i
Figure 16. Remote On/Off Implementation
Remote Sense
Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections. The voltage between the remote-sense
pins and the output terminals must not exceed the out-
put voltage sense range giv en in the Feature Specifica-
tions table, for example, for the CC030Bs:
[VO(+) – VO(–)] – [SENSE(+) – SENSE(–)] ≤ 0.5 V
The voltage between the VO(+) and VO(–) terminals
must not exceed 13.2 V. This limit includes any
increase in voltage due to remote-sense compensa-
tion, set-point adjustment, and trim (see Figure 17).

Figure 17. Effective Circuit Configuration for
Single-Module Remote-Sense Operation
Output V oltage Adjustment
Output voltage adjustment allows the user to increase
or decrease the output voltage set point of a module.
This is accomplished by connecting an e xternal resistor
between the TRIM pin and either the SENSE(+) or
SENSE(–) pins (see Figures 18 and 19). With an exter-
nal resistor between the TRIM and SENSE(–) pins
(Radj-up), the output voltage set point (VO, adj) increases.
The value of the internal resistor R1 is shown in Table 4.
Table 4. Internal Resistor Values
With an external resistor connected between the TRIM
and SENSE(+) pins (Radj-down), the output voltage set
point (VO, adj) decreases.
The combination of the output voltage adjustment
range and the output voltage sense range given in the
Feature Specifications table cannot exceed 110% of
the nominal output voltage between the Vo(+) and
Vo(–) terminals.
The CC030-Series Power Modules have a fixed cur-
rent-limit set point. Therefore, as the output voltage is
adjusted down, the available 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, which is independent of the primary regulation
loop that monitors the voltage on the output terminals.
The control loop of the clamp has a higher voltage set
point than the primary loop (see Feature Specifications
table). This provides a redundant voltage-control that
reduces the risk of output overvoltage.

Thermal Considerations
The CC030-Series Power Modules are designed to
operate in a variety of thermal environments. As with
any electronic component, sufficient cooling must be
provided to help ensure reliable operation. Heat-dissi-
pating components inside the module are thermally
coupled to the case to enable heat removal by conduc-
tion, convection, and radiation to the surrounding envi-
ronment.
The thermal data presented is based on measurements
taken in a wind tunnel. The test setup shown in Figure
20 was used to collect data for Figures 24 and 25.
The graphs in Figures 21 through 23 provide general
guidelines for use. Actual performance can vary
depending on the particular application environment.
The maximum case temperature of 100 °C m ust not be
exceeded.
Basic Thermal Performance
The CC030-Series Power Modules are constructed
with a specially designed, heat spreading enclosures.
As a result, full load operation in natural convection at
50 °C can be achieved without the use of an external
heat sink.
Higher ambient temperatures can be sustained by
increasing the airflow or by adding a heat sink. As
stated, this data is based on a maximum case temper-
ature of 100 °C and measured in the test configuration
shown in Figure 20.

Thermal Considerations (continued)
Forced Convection Cooling
To determine the necessary airflow, determine the
power dissipated by the unit for the particular applica-
tion. Figures 21 through 23 show typical power dissipa-
tion for these power modules over a range of output
currents. With the kno wn po wer dissipation and a giv en
local ambient temperature, the appropriate airflow can
be chosen from the derating curves in Figure 24. For
example, if the unit dissipates 6.2 W, the minimum air-
flow in a 80 °C environment is 1.0 ms–1 (200 ft./min).

Thermal Considerations (continued)
Heat Sink Selection
Se ver al heat sinks are av ailab le for these modules . The
case includes through threaded mounting holes allow-
ing attachment of heat sinks or cold plates from either
side of the module. The mounting torque must not
exceed 0.56 N-m (5 in.-lb).
Figure 25 shows the case-to-ambient thermal resis-
tance, θ (°C/W), for these modules. These curves can
be used to predict which heat sink will be needed for a
particular environment. For example, if the unit dissi-
pates 7.1 W of heat in an 80 °C environment with an
airflow of 0.5 ms–1 (100 ft./min.), the minimum heat
sink required can be determined as follows:
where:
θ = module's total thermal resistance
Tc, max = case temperature (See Figure 20.)
TA = inlet ambient temperature
(See Figure 20.)
PD = power dissipation
θ ≤ (100 – 80)/7.1
θ ≤ 2.8 °C/W
From Figure 25, the 1/2 in. high heat sink or greater is
required.
8-1157(C).c
Figure 25. Case-to-Ambient Thermal Resistance vs.
Air Velocity Curves; Either Orientation
Although the previous example uses 100 °C as the
maximum case temperature, f or extremely high-reliabil-
ity applications, one can use a lower temperature for
Tc, max.
It is important to point out that the thermal resistances
shown in Figure 25 are for heat transfer from the sides
and bottom of the module as well as the top side with
the attached heat sink; therefore, the case-to-ambient
thermal resistances shown will generally be lower than
the resistance of the heat sink by itself. The data in Fig-
ure 25 was taken with a thermally conductive dry pad
between the case and the heat sink to minimize contact
resistance (typically 0.1 °C/W to 0.3 °C/W).

management for this series of power modules as well
