Description
The JC030-Series Power Modules are dc-dc converters that operate over an input voltage range of 18 Vdc to
36 Vdc and provide precisely regulated 2 V, 5 V, 12 V, and 15 V outputs. The outputs are isolated from the
inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum
power ratings of 30 W at a typical full-load efficiency of 81%.
The power modules feature remote on/off, output sense (both negative and positive leads), and output voltage
adjustment, which allows output voltage adjustment from 60% to 110% (80% to 110% for the JC030A-M and
JC030D-M) of the nominal output voltage. For disk-drive applications, the JC030B-M Power Module provides a
motor-start surge current of 3 A.
The modules are PC-board mountable and encapsulated in metal cases. The modules are rated to full load at
100 °C case temperature with no external filtering.

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.

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
fusing 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 (see Safety Considerations 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.

Remote On/Off
Design Considerations
Grounding Considerations
Two remote on/off options are available. Positive logic
remote on/off turns the module on during a logic-high
voltage on the remote ON/OFF pin, and off during a
logic low. Negative logic remote on/off, device code
suffix “1,” turns the module off during a logic high and
on during a logic low. Standard modules provide posi-
tive logic remote on/off.
The power module has an isolated case ground pin.
The case is not connected internally allowing the user
flexibility in grounding.
Input Source Impedance
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 22). A logic low is Von/off = –0.7 V to 1.2 V. The
maximum Ion/off during a logic low is 1 mA. The switch
should maintain a logic-low voltage while sinking 1 mA.
The power module should be connected to a low ac-
impedance input source. Highly inductive source
impedances can affect the stability of the power mod-
ule. A 33 µF electrolytic capacitor (ESR < 0.7 ¾ at
100 kHz) mounted close to the power module helps
ensure stability of the unit.
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.
Safety Considerations
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.
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).
CAUTION: To avoid damaging the power module or
external on/off circuit, the connection
between the VI(–) pin and the input
source must be made before or simulta-

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 exhibit either foldback or tai-
lout characteristics (output current decrease or

Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense

equation determines the required external resistor
value to obtain an output voltage change of %ý.

The voltage between the VO(+) and VO(–) terminals
must not exceed the minimum output overvoltage shut-

The JC030 Power Module family has a fixed current-
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 voltage trim allows the user to increase or

Feature Descriptions (continued)
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 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.

The JC030-Series Power Modules are designed to
operate in a variety of thermal environments. As with
any electronic component, sufficient cooling must be
5
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.

modules may be used typically generate natural con-

other heat dissipating components in the system.
The graphs in Figures 27 through 32 provide general
guidelines for use. Actual performance can vary

Basic Thermal Performance

The JC030-Series power modules are built with a spe-

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 tempera-
ture of 100 °C and measured in the test configuration
shown in Figure 26.

Forced Convection Cooling
To determine the necessary airflow, determine the
power dissipated by the unit for the particular applica-
tion. Figures 27 through 30 show typical power dissipa-
tion for those power modules over a range of output
currents. With the known power dissipation and a given
local ambient temperature, the appropriate airflow can
be chosen from the derating curves in Figure 31. For
example, if the unit dissipates 6.2 W, the minimum air-
–1
flow in an 80 °C environment is 1.02 ms
(200 ft./min.).

Although the previous example uses 100 °C as the

Thermal Considerations (continued)
Heat Sink Selection (continued)
The thermal resistances shown in Figure 32 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 Figure 32 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).
