DESIGN CONSIDERATIONS
Layout and EMC Considerations
Delta’s DC/DC power modules are designed to
operate in a wide variety of systems and applications.
For design assistance with EMC compliance and
related PWB layout issues, please contact Delta’s
technical support team.
Schematic and Components List
Remote On/Off
The remote on/off feature on the module is negative logic.
Negative logic turns the module on during logic low and off
during logic high. Remote on/off can be controlled by an
external switch between the on/off terminal and the Vin(-)
terminal. The switch can be an open collector or open drain.
For negative logic if the remote on/off feature is not used,
please short the on/off pin to Vin(-).

Output Voltage Set Point
The output voltage can be programmed to any voltage
between 0Vdc and 60Vdc by connecting one resistor, R(Vset),
between the Vset pin (9) and Vout- pin (7); See Figure 15. For
a desired output voltage, the value of the resistor should be:
714900
R Vset(Vset ) = [(
) − 10870](Ω)
Vo + 3.459
Alternatively, the Vset pin can be driven from an external
voltage source:
𝑉𝑉𝑠𝑒𝑡(𝑉𝑠𝑒𝑡) = 2.366 − 0.038𝑉𝑜
Vo = desired output voltage set point
Undriven, this pin floats at 2.5V which sets the
output to 0V.
Short CASE to Ground in EMC test
Safety Considerations
The power module must be installed in compliance with the
spacing and separation requirements of the end-user’s safety
agency standard, i.e. IEC 62368-1: 2014 (2nd edition), EN
62368-1: 2014 (2nd edition), UL 62368-1, 2nd Edition,
2014-12-01 and CSA C22.2 No. 62368-1-14, 2nd Edition,
2014-12. UL60950-1, CSA C22.2 NO. 60950-1 2nd, IEC
60950-1 2nd: 2005, EN 60950-1 2nd: 2006+A11+A1: 2010, if
the system in which the power module is to be used must meet
safety agency requirements.
Both the input and output of this product meet SELV
requirement.
This power module is not internally fused. To achieve
optimum safety and system protection, an input line fuse is
highly recommended. The safety agencies require a
normal-blow fuse with 70A maximum rating to be installed in
the ungrounded lead. A lower rated fuse can be used based
on the maximum inrush transient energy and maximum input
current.
Two rated 40A/72Vdc external fuse in parallel, from Littelfuse
type 456 series.
The equipment shall be supplied from a DC source that
provides double/reinforced insulation from AC mains.
Datasheet
DS_H60SB0A050_01252021
Figure 15
R(Vset) or the external voltage source should be connected
to Vout- pin (7) directly to minimize impact of parasitic
parameter;
Output Current Setting
The maximum output current (effectively the current limit) can
be reduced to any value between 0 and Imax by connecting
one resistor, R(Iset), between the Iset pin (4) and Vin- pin (6);
see Figure 15. The value of the resistor should be:
25Iset
R Iset(Iset) =
(kΩ)
3.3Imax − 2.5Iset
Alternatively, the Iset pin can be driven from an external
voltage source:
Iset
VIset(Iset) = 2.5 ×
Imax
Iset = desired output current set point
Imax = maximum rated output current (50A)
Undriven, Iset pin floats to 3.3V which sets the current limit
at its nominal value of 110% * Imax.
R(Iset) or the external voltage source should be connected
to Vin- pin (6) directly to minimize impact of parasitic
parameter;

DESIGN CONSIDERATIONS
Over-Current Protection
The modules include an internal output over-current
protection circuit, which will endure current limiting for an
unlimited duration during output overload. If the output
current exceeds the OCP set point, the modules will shut
down (hiccup mode). The modules will try to restart after
shutdown. If the overload condition still exists, the module
will shut down again. This restart trial will continue until the
overload condition is removed.
Over-Voltage Protection
The modules include an internal input over-voltage
protection circuit and output voltage protection circuit, which
monitors the voltage on the input terminals and the output
terminals. If this voltage exceeds the over-voltage set point,
the protection circuit will shut down, and enter latch mode.
Need to repower input voltage or reset ON/OFF pin voltage
to turn on the module.
Over-Temperature Protection
The over-temperature protection consists of circuitry that
provides protection from thermal damage. If the temperature
exceeds the over-temperature threshold the module will shut
down. The module will restart after the temperature is within
specification.
Parallel
The modules provide active current sharing mode.
For the active current sharing: it permits maximum 8%
output voltage deviation between two modules by
connecting the Vout pin and Ishare pin of the parallel module
together, the current sharing can be realized automatically.
The module can be parallel directly for higher power without
adding external oring-fet. And the failure of a power supply
should not affect the load sharing or output voltages of the
other supplies still operation
For a normal parallel operation, the following precautions
must be observed:
1. The current sharing accuracy equation is:
X% = | Io1–Io2 | / Irate, Where,
Io1 is the output current of module1;
Io2 is the output current of module2
Irate is the rated full load current of per module.
2. To ensure a better steady current sharing accuracy, below
design guideline should be followed:
a) The inputs of the converters must be connected to the
same voltage source; and the PCB trace resistance from
Input voltage source to Vin+ and Vin- of each converter
should be equalized as much as possible.
b) The PCB trace resistance from each converter’s output
to the load should be equalized as much as possible.
c) For accurate current sharing accuracy test, the module
should be soldered in order to avoid the unbalance of the
touch resistance between the modules to the test board.
3. To ensure the parallel module can start up monotonically
without trigging the OCP circuit, below design guideline
should be followed:
a) Before all the parallel modules finished start up, the total
load current should be lower than the rated current of 1
module.
b) The ON/OFF pin of the converters should be connected
together to keep the parallel modules start up at the same
time.
c) The under voltage lockout point will slightly vary from
unit to unit. The dv/dt of the rising edge of the input source
voltage must be greater than 1V/ms to ensure that the
parallel module start up at the same time.
Soldering and Cleaning Considerations
Post solder cleaning is usually the final board assembly
process before the board or system undergoes electrical
testing. Inadequate cleaning and/or drying may lower the
reliability of a power module and severely affect the finished
circuit board assembly test. Adequate cleaning and/or drying
is especially important for un-encapsulated and/or open
frame type power modules. For assistance on appropriate
soldering and cleaning procedures, please contact Delta’s
technical support team.

PMBUS COMMUNICATION
PMBus Communication
The module has a digital PMBus interface to allow the
module to be monitored, controlled and configured by the
system. The module supports 3 PMBus signal lines, Data,
Clock, SMBALERT (optional), and 2 Address line Addr0 and
Addr1. More detail PMBus information can be found in the
PMB Power Management Protocol Specification, Part I and
part II, revision 1.2; which is shown in http://pmbus.org .
Both 100kHz and 400kHz bus speeds are supported by the
module. Connection for the PMBus interface should be
following the High Power DC specifications given in section
3.1.3 in the SMBus specification V2.0 or the Low Power DC
specifications in section 3.1.2. The complete SMBus
specification is shown in http://smbus.org.
The module supports the Packet Error Checking (PEC)
protocol. It can check the PEC byte provided by the PMBus
master, and include a PEC byte in all message responses to
the master.
SMBALERT protocol is also supported by the module.
SMBALERT line is also a wired-AND signal; by which the
module can alert the PMBUS master via pulling the
SMBALERT pin to an active low. There are two ways that
the master and the module response to the alert of
SMBALERT line.
One way is for the module used in a system that does not
support Alert Response Address (ARA). The module is to
retain its resistor programmed address, when it is in an
ALERT active condition. The master will communicate with
the slave module using the programmed address, and using
the various READ_STATUS commands to find who cause
for the SMBALERT. The CLEAR_FAULTS command will
clear the SMBALERT.
The module contains a data flash used to store configuration
settings, which will not be programmed into the device data
flash automatically. The STORE_DEFAULT_ALL command
must be used to commit the current settings are transfer
from RAM to data flash as device defaults
PMBUS Addressing
The Module has flexible PMBUS addressing capability.
When connect different resistor from Addr0 and Addr1
pin to GND pin, 64 possible addresses can be
acquired. The address is in the form of octal digits;
Each pin offers one octal digit, and then combine
together to form the decimal address as shown in
below.
Address = 8 * ADDR1 + ADDR0
Corresponded to each octal digit, the requested
resistor values are shown in below, and +/-1%
resistors accuracy can be accepted. If there are any
resistances exceeding the requested range,
address 127 will be return. 0-12 and 40, 44, 45, and
55 in decimal address can’t be used, since they are
reserved according to the SMBus specifications,
and which will also return address 127.

PMBus Data Format
The module receives and report date in LINEAR format.
altering the exponent is supported. DIRECT format is
not supported by the module.
For commands that set or report any voltage thresholds
related to the output voltage, the module supports the
linear data format consisting of a two-byte value with a
16-bit, unsigned mantissa, and a fixed exponent of -9.
The format of the two data bytes is shown below:
The equation can be written as:
Vout = Mantissa x 2-9
For example, considering set Vout to 12V by
VOUT_COMMAND, the read/write data can be
calculated refer to below process:
1. Mantissa =Vout/2-9= 12/2-9=6144;
2. Converter the calculated Mantissa to hexadecimal
0x1800.
For commands that set including input voltages,
output current, temperature, time and frequency,
the format of the two data bytes is shown as in
below:
For example, considering set the turn on threshold of
input under voltage lockout to 34V by VIN_ON command;
the read/write data can be calculated refer to below
process:
1. The read Vin value is hexadecimal E910
2. The high 5 bit in binary is 11101, so the Mantissa is
2-3.
3. Low 11 bits 00100010000, in decimal is 272
4. So the real Vin value is 272/2-3 is 34v.

Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power module
should always be operated below the maximum operating
temperature. If the temperature exceeds the maximum
module temperature, reliability of the unit may be affected.

MANUFACTURE CONSIDERATIONS
Soldering Method
Generally, as the most common mass soldering method for the solder attachment, wave soldering is used for
through-hole power modules and reflow soldering is used for surface-mount ones. Delta recommended soldering
methods and process parameters are provided in this document for solder attachment of power modules onto system
board. SAC305 is the suggested lead-free solder alloy for all soldering methods.
Wave Soldering (Lead-free)
Delta’s power modules are designed to be compatible with single-wave or dual wave soldering. The suggested
soldering process must keep the power module’s internal temperature below the critical temperature of 217℃
continuously. The recommended wave-soldering profile is shown in following figure.
Recommended Temperature Profile for Lead-free Wave Soldering
Note: The temperature is measured on solder joint of pins of power module.
The typical recommended (for double-side circuit board) preheat temperature is 115+/-10℃ on the top side
(component side) of the circuit board. The circuit-board bottom-side preheat temperature is typically recommended to
be greater than 135℃ and preferably within 100℃ of the solder-wave temperature. A maximum recommended
preheat up rate is 3℃ /s. A maximum recommended solder pot temperature is 255+/-5℃ with solder-wave dwell time
of 3~6 seconds. The cooling down rate is typically recommended to be 6℃/s maximum.
Hand Soldering (Lead Free)
Hand soldering is the least preferred method because the amount of solder applied, the time the soldering iron is held
on the joint, the temperature of the iron, and the temperature of the solder joint are variable. The recommended hand
soldering guideline is listed in Table 1. The suggested soldering process must keep the power module’s internal
temperature below the critical temperature of 217℃ continuously.
