Note: Scope measurements should be made using a BNC socket
with a 1µF ceramic capacitor and a 10µF tantalum capacitor.
Position the oscilloscope probe between 51mm and 76mm
(2in and 3in) from the module
Note: Measure input reflected ripple current with a simulated
source inductance of 12µH. The measurement points for input
reflected ripple current is showed above.
Design considerations
Input filtering
The power module should be connected to a low acimpedance input source. Highly inductive source impedances can affect the stability of the
power module. For the test configuration in Figure7 a 470µF electrolytic capacitor and a 1µF ceramic capacitor, mounted close to the power
module helps ensure stability of the unit.
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. UL60950-1, CAN/CSA-C22.2, No. 60950-1 and
EN60950-1:2001(+A11)andIEC60950-1:2005,ifthesysteminwhichthe
power module is to be used must meet safety agency requirements.
If the input source is non-SELV (ELV or hazardous voltage greater than
60Vdc and less than or equal to 75Vdc), for the module’s output to be
considered as meeting the requirements for safety extra-low voltage
(SELV), all of the following must be true.
1. The input source is to be provided with reinforced insulation from
any other hazardous voltage, including the AC mains.
2. One VIN pin and one VOUT pin are to be grounded, orboth the input
and output pins are to be kept floating.
These converters have been evaluated to the spacing requirements
for Basic Insulation, per the above safety standards.
3. The input pins of the module are not operatoraccessible.
4. Another SELV reliability test is conducted on the whole system as
required by the safety agencies, to verify that under a single fault,
hazardous voltages do not appear at the module’s output.
For all input voltages, other than DC mains, where the input volta-
ge is less than 60Vdc, if the input meets all of the requirements for
SELV, the output is considered to remain with SELV limits. Signal
component failure and fault tests were performed in the power
converters.
All flammable materials used in the manufacturing of these modules
are rated 94V-0.
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 time delay fuse
with a maximum rating of 30A. 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 sheet for further information.

700 W Half-Brick - Single Output DC-DC Converter - Wide Input - Isolated & Regulated
Feature descriptions
Remote on/off
The REM pin is used to turn the power converter remote on or off via a system
signal. Two remote on/off logic are available. Negative logic turns the module
on when the REM pin is at logic low and off when it is at logic high. Positive
logic turns the module on during logic high and off during logic low.
To turn the power module on and off, the user must supply a switch to control
the voltage between the REM pin and -Vin terminal (see Figure 9). A logic low is
VREM =0.3 to 0.8 V. During logic high, the maximum VREM voltage generated
by the power module is 20V. If not using the remote on/off feature, perform
one of the following to turn the converter on:
For negative logic, short REM pin to -Vin.
For positive logic, leave REM pin open.
Remote sense
Remote sense minimizes the effects of distribution losses by
regulating the voltage at the remote sense connections (see Figure 10).
The voltage between the remote sense pins and the output terminals must
not exceed the output voltage sense range. The voltage between the +Vo1
and GND terminals must not exceed the minimum output overvoltage
protection value shown in the Electrical Specifications table. This limit includes
any increase in voltage due to remote sense compensation and output voltage
programming (trim). If not using the remote sense feature to regulate the
output at the point of load, then connect +S to +VO1 and -S to GND. Although
the output voltage can be increased by both the remote sense and by the
trim, the maximum increase for the output voltage is not the sum of both. The
maximum increase is the larger of either the remote sense or the trim.
The amount of power delivered by the module is defined as the voltage at
the output terminals multiplied by the output current. When using remote
sense and trim, the output voltage of the module can be increased, which at
the same time the output current would increase the power output of the
module. Care should be taken to ensure that the maximum output power of
the module remains at or below the maximum rated power.
Output Voltage Programming
When trimming up, the output current should be decreased
accordingly so as not to exceed the maximum output power
and the minimum input voltage should be increased as
shown in the Figure 11 and Figure 12.
Resistance adjustment mode
Output voltage trim allows the user to increase or decrease the outout
voltage set point of a module. This is accomplished by connecting an
external resistor between the TRIM pin and either the +S or -S pins. If not
using the trim feature, leave the TRIM pin open. To increase the output
voltage, refer to Figure13. A trim resistor, Rtrimup, connect between the TRIM
pin and +S pin.
Figure11. Max. adjustable output voltage vs. input
Figure12. Circuit Configuration to Increase Output
Trimming beyond 57.6V is not an acceptable design practice, as this condi-
tion could cause unwanted triggering of the output overvoltage protection
(OVP) circuit. When trimming up, care must be taken not to exceed the
converter’s maximum allowable output power. To decrease the output
voltage (see Figure14.), a trim resistor, Rtrimdown, should be connected
between the TRIM and -S, with a value of

Protection features
Over current Protection
Over temperature Protection
To provide protection under certain fault conditions, the
To provide protection in an output overload fault condition, the
module is equipped with internal current limiting circuitry, and can
endure current limiting continuously. At the point of current limit
inception, the unit enters hiccup mode. The unit is configured with
the auto-restart function, it will remain in the hiccup mode as long
as the overcurrent condition exists, it operates normally once the
output current is reduced back into its specified range.
Output Overvoltage Protection
module is equipped with
a thermal shutdown circuit. The
module will shutdown when the aluminum baseplate
temperature exceeds OTP set value, but the thermal
shutdown is not intended as
a guarantee that the module
will survive when the temperatures beyond its rating. The
module will automatically restarts after it cools down.
The output over voltage protection consists of circuitry that
monitors the voltage on the output terminals. When the output
voltage exceeds the overvoltage protection threshold, the module
will operate in a hiccup mode until overvoltage cause is cleared.
Input Undervoltage Lockout
Input under-voltage lockout is standard with this converter, when
input voltages below the input under-voltage lockout limit, the
module operation is disabled. It will only begin to operate once
the input voltage is raised above the undervoltage lockout turn-on
threshold
Thermal considerations
The power modules operate in a variety of thermal environments;
however, sufficient cooling should be provided to help ensure reliable
operation of the unit.
Through-Hole Soldering Information
The product is intended for through-hole mounting in a PCB. When
wave soldering is used, the temperature on the pins is specified to
maximum 270 °C for maximum 10 seconds.
Considerations include ambient temperature, airflow, module power
dissipation, and the need for increased reliability. A reduction in the
operating temperature of the module will result in an increase in
reliability.
Maximum preheat rate of 4 °C/s and temperature of max 150 °C is
suggested, when hands soldering care should be taken to avoid direct
contact between the hot soldering iron tip and the pins for more than
a few seconds in order to prevent overheating.
A no-clean (NC) flux is recommended to avoid entrapment of A
noclean (NC) flux is recommended to avoid entrapment of cleaning
fluids in cavities inside of the DC-DC power module. The residues may
affect long time reliability and isolation voltage.
EMC Considerations
The Figure 20 shows a suggested configuration to meet the
conducted emission limits of EN55022 Class B.
