Description
The HHS60 Series of high-density, single-output dc-dc converters is ideal for telecom and datacom systems that
require low voltage at high current in an industry-standard, half-brick footprint. Highly efficient topology and
thermally-optimized construction allow the units to provide high output current in the system over a wide operating
temperature range while still maintaining a safe guardband for component electrical and thermal ratings. The
addition of an external heat sink increases the capacity of the unit. The HHS60 employs 100% surface-mount
components for consistency and reliability in our production process, and is available in four standard output
voltages from 1.5 to 3.3 VDC.

The customer may elect to operate the HHS60ZE at
a TBP of 115 OC thereby extending the operating
current ratings as defined by the “200 LFM @
TBP=115 OC” derating curve above. This condition
can be instrumental towards compliance of
GR-63-CORE, sect.: 4.1.2 defining “short term”
temperature conditions.
However the HHS60 series power derating curves of
all models are otherwise characterized at a more
conservative baseplate temperature (TBP) of 110 OC.
This recommended maximum operating temperature
offers improved reliability.

Vin = 48Vdc, Scale is 20Amp/Div.
Once the output current is brought back into its
specified range, the converter automatically exits the
hiccup mode and continues normal operation.
Overvoltage Protection
The output overvoltage protection consists of a
separate control loop, independent of the primary
control loop. This control loop has a higher voltage
set point than the primary loop. In a fault condition
the converter limits its output voltage and latches off.
Figure 14 shows operation of the converter under an
overvoltage condition.
The HHS60 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 100 μF electrolytic
capacitor with the ESR < 0.7Ω is recommended for
the HHS60 series.
If the magnitude of the inrush current needs to be
limited, for suggestions see the “Inrush Current
Control Application Note” on the Power-One website
at www.power-one.com.
For output decoupling we recommend using one
10μF tantalum and one 1μF ceramic capacitors
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 (# 3) pin of the HHS60 Series
converters is referenced to the –Vin (# 1) pin (see
Figure 5). Both negative and positive logic models
are available.
With negative logic (which is denoted by the suffix “–
N” in the part number), when the ON/OFF pin is
pulled low, the unit is turned on.
With the 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.

HHS60 DC-DC Series Data Sheet
48VDC Input, 60 Amp Half-Brick Converter
Negative Trim (No P/N suffix)
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 (# 4) pin.
All HHS60 negative-trim models trim up with a
resistor connected from the TRIM (#7) pin to the
(-) Sense (#6) pin and trim down with a resistor from
the TRIM pin to the (+) Sense (#8) pin as shown in
Figure 16.
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 actually 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.
Note:
If the ON/OFF pin is not used, it can be left floating (positive logic),
or connected to the -Vin pin (negative logic).
Remote Sense
The HHS60 Series converters have the capability to
remotely sense both lines of the output. This feature
moves the effective output voltage regulation point
from the output of the unit to the point of connection
of the remote sense pins. This feature automatically
adjusts the real output voltage of the converter in
order to compensate for voltage drops in distribution
and maintain a regulated voltage at the point of load.
This is shown in Figures 16 & 17.
Figure 16. HHS60 Series Negative Trim Schematic
The following equation determines the required
external resistor value to obtain an output voltage
change of Δ%.
Vo*(100-Δ%)-122.5
Rtrim-dn = R1*(--------------------------- ) - R2 kΩ
Vo*Δ%
If the remote sense feature is not to be used, the
sense pins should be connected locally.
The
+Sense (#8) pin should be connected to the +Vout
(#9) pin directly at the output of the converter and the
–Sense (#6) pin should be connected to the -Vout
(#5) pin directly at the output of the converter.
If sense pins are not connected to load, or the
respective output pins, the converter will not be
damaged, but may not meet the output voltage
regulation specifications.

Output Voltage Trim
The trim feature allows the user to adjust the output
voltage from the nominal value. This can be used to
compensate for distribution drops, perform margining
in production, or accommodate other requirements
when output voltage needs to be adjusted from the
nominal value. There are two trim options available
in the HHS60 Series.

Optional Positive-Trim (–T, P/N suffix)
The trim feature allows the user to adjust the output
voltage from its nominal value.
The HHS60 positive-trim (-T) models trim up with a
resistor from the Trim (#7) pin to the +Sense (#8) pin
and trims down with a resistor from the Trim pin to
the –Sense (#6) pin as shown in the Figure 17.

Either Rup or Rdown should be used to adjust the output

Safety Considerations
The HHS60 Series converters feature 1500 VDC
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 other or additional requirements may be
needed for specific applications.

The equations below determine the trim resistor
value required to achieve a ΔV change in the output
voltage.

Vo*(100+Δ%)
In order for the output of the HHS60 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:
(100+2*Δ%)
Rtrim-up = (-------------------- - ------------------) kΩ
1.225*Δ%
The HHS60 Series converters have no internal fuse.
An external fuse must be provided to protect the
system from catastrophic failure, as illustrated in
figure 15. Refer to the “Input Fuse Selection for
DC/DC converters” application note on www.powerone.com for proper selection of the input fuse. 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.

where ΔV% is the output voltage change expressed

•
Notes:
1. When the output voltage is trimmed up, the output power
from the converter must not exceed its maximum rating. The
power is determined by measuring the output voltage on the
output pins, and multiplying it by the output current.
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
2.
3.
In order to avoid creating apparent load regulation
degradation, it is important that the trim resistors are
connected directly to the remote sense pins, and not to the
load or to traces going to the load.
The output voltage increase can be accomplished by either
the trim or by the remote sense or by the combination of
both. In any case the absolute maximum output voltage

voltages.
The entire system, including the
HHS60 converter, must pass a dielectric
withstand test for Reinforced insulation. Design
of this type of systems requires expert
engineering and under-standing of the overall
safety requirements and should be performed by
qualified personnel.

determined by meeting the derating criteria for all
components used in the converters. For example,
the maximum semiconductor junction temperature is
not allowed to exceed 120 °C to ensure reliable longterm operation of the converters.
