Description
The HHD25 is a series of high density Half-brick size, High current, Dual output dc-dc converters with through-hole
mounting. The products provide onboard conversion of standard telecom and datacom input voltages to two
independently-regulated output voltages. Leading-edge technology provides extremely high efficiency and
superior thermal performance which enables the products to deliver full-rated power at 55 °C ambient temperature
with only 200 LFM forced air without the addition of a heatsink. The outputs also track each other during both
startup and shutdown.

When the ON/OFF pin is used to achieve remote
control, the user must take care to insure that the pin
reference for the control is really the -Vin pin. The
control signal must not be referenced ahead of EMI
filtering, or remotely from the unit. Optically coupling
the information and locating the optical coupler
directly at the module will solve any of these
problems.
Typical Application
Figure 5 shows recommended connections for the
HHD Series converter.
Note:
If the ON/OFF pin is not used, it can be left floating (positive logic),
or connected to the -Vin pin (negative logic).
Output Voltage Trim
The trim feature allows the user to adjust the output
voltage from the nominal. This can be used to
accommodate a different requirement or to do
production margin testing.
Figure 5. Typical Application of HHD Series
The HHD Series converters do not require any
external components for proper operation. However,
if the distribution of the input voltage to the converter
contains significant inductance, the capacitor C1
may be required to enhance performance of the
converter. A minimum of a 47 μF electrolytic
capacitor with the ESR<0.7Ω is recommended for
the HHD Series.
The general equation for changing the output voltage
on the standard trim modules is invariant, but the
internal values are different for different output
voltages, so the constants in the equation change.

If the magnitude of the inrush current needs to be
limited, see the “Inrush Current Control Application
Note” on www.power-one.com.
where A and B are constants from the table below,
and ΔV is the absolute value of the desired change
in the output voltage in Volts.
For output decoupling, we recommend using a 10 μF
tantalum and a 1 μF ceramic capacitor connected
directly across the output pins of the converter. Note
that the capacitors do not substitute the filtering
required by the load.

Shutdown Feature Description
The ON/OFF pin in the HHD Series converters
functions as a normal soft shutdown. It is referenced
to the –Vin pin (see Figure 5). With the standard
positive logic, when the ON/OFF pin is pulled low,
the output is turned off and the unit goes into a very
low input power mode.

With optional negative logic, when the ON/OFF pin is
pulled low, the unit is turned on.
An open collector switch is recommended to control
the voltage between the ON/OFF pin and the -Vin
pin of the converter. The ON/OFF pin is pulled up
internally, so no external voltage source is required.
The user should avoid connecting a resistor between
the ON/OFF pin and the +Vin pin.

HHD25 DC-DC Series Data Sheet
20/25A Half-Brick
The HHD Series converters feature 1500 Volt DC
isolation from input to output. The input-to-output
resistance is greater than 10MΩ. These converters
are provided with Basic insulation between input and
output circuits according to all IEC60950 based
standards. Nevertheless, if the system using the
converter needs to receive safety agency approval,
certain rules must be followed in the design of the
system. In particular, all of the creepage and
clearance requirements of the end-use safety
requirements must be observed. These documents
include UL60950 - CSA60950-00 and EN60950,
although specific applications may have other or
additional requirements.
Thermal Considerations
The HHD Series converters are designed for natural
or forced convection cooling. The output power of
the converters is determined by the maximum
semiconductor junction temperature. To provide
reliable long-term operation of the converters,
Power-One limits maximum allowable junction
temperature to 120 °C.
The graphs in Figures 6-9 show the maximum output
current of the HHD Series converters at different
local ambient temperatures at both natural and
forced (longitudinal airflow direction, from pin 1 to
pin 4) convection.
The HHD Series converters have no internal fuse.
The external fuse must be provided to protect the
system from catastrophic failure. The fuse with a
rating not greater than 10 A is recommended. The
user can select a lower rating fuse based upon the
inrush transient and the maximum input current of
the converter, which occurs at the minimum input
voltage. Both input traces and the chassis ground
trace (if applicable) must be capable of conducting a
current of 1.5 times the value of the fuse without
opening. The fuse must not be placed in the
grounded input line, if any.
In order for the output of the HHD Series converter to
be considered as SELV (Safety Extra Low Voltage)
or TNV-1, according to all IEC60950 based
standards, one of the following requirements must be
met in the system design:
•
If the voltage source feeding the module is SELV
or TNV-2, the output of the converter may be
grounded or ungrounded.
•
If the voltage source feeding the module is ELV,
the output of the converter may be considered
SELV only if the output is grounded per the
requirements of the standard.
•
If the voltage source feeding the module is a
Hazardous Voltage Secondary Circuit, the
voltage source feeding the module must be
provided with at least Basic insulation between
the source to the converter and any hazardous
voltages. The entire system, including the HHD
converter, must pass a dielectric withstand test
for reinforced insulation. Design of this type of
system requires expert engineering and under-
standing of the overall safety requirements and
should be performed by qualified personnel.
