The 450HBAW_1.5 series are half-brick DC-DC converters that provide
high efficiency single output. They can operate from 36VDC to 75VDC
input and 48V/9.4A output. The output can be trimmed from -50% to
+20% of normal output voltage. The remote on/off feature on the
module can be either negative or positive logic. Negative logic turns
the module on during a logic low and off during a logic high. Positive
logic turns the modules on during a logic high and off during a logic
low.

Note: Measure input reflected ripple current with a simulated

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,
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.
CAN/CSA-C22.2, No. 60950-1 and EN60950-1:2001(+A11)
and IEC60950-1:2005, if the system in which the power
module is to be used must meet safety agency requirements.
• The input source is to be provided with reinforced insulation from any
other hazardous voltage, including the AC mains.
• 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.
• The input pins of the module are not operatoraccessible.
• 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
voltage 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 20A. 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

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 to 1.2 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 (<1V). 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
Resistance adjustment mode
Output voltage trim allows the user to increase or decrease the output
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 figure 11. A trim resistor, Rtrimup, con-
nected between the TRIM and +S pin.
Figure11. Circuit Configuration to Increase
Output Voltage.
Trimming beyond 120% of the rated output voltage is not an acceptable
design practice, as this condition could cause unwanted triggering of the
output over-voltage 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 Figure12.), a trim resistor, Rtrimdown,
should be connected between the TRIM and -S, with a value of
Figure12. Circuit Configuration to Decrease
Output Voltage.

Protection features
Over current Protection
equipped with a thermal shutdown circuit. The module will shutdown
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
when the aluminum baseplate temperature exceeds required tempe-
rature in the protection characteristics, 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.
Input Undervoltage Lockout
Input under-voltage lockout is standard with this converter, when
input voltages below the input under-voltage lockout limit, the mo-
dule operation is disabled. It will only begin to operate once the input
voltage is raised above the undervoltage lockout turn-on threshold
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.
Over temperature Protection
To provide protection under certain fault conditions, the module is
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 re-
liability.
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 no-
clean (NC) flux is recommended to avoid entrapment of cleaning flu-
ids in cavities inside of the DC/DC power module. The residues may
affect long time reliability andisolation voltage.
EMC Considerations
The Figure 13 shows a suggested configuration to meet the conducted
emission limits of EN55022 Class B.
