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 heatsink 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 V to 3.3 V.

Figure 15. Typical Application of the HHS60 Series
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
Figure 13 Output current with shorted output pins,
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.
converter.
A minimum of a 100µF electrolytic
capacitor with the ESR<0.7Ω is recommended for
the HHS60 series.
Overvoltage Protection
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.
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.
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 are 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.

REV. OCT 24, 2003
Page 8 of 12
HHS60 DC/DC Series Data Sheet
48Vdc Input, 60-Amp Half-Brick Converter
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.
Negative Trim (No P/N suffix)
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.
The user should avoid connecting a resistor between
the ON/OFF pin and the +Vin (# 4) pin.
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.

The following equation determines the required
external resistor value to obtain an output voltage
change of ∆%.

If the remote sense feature is not to be used, the

The trim feature allows the user to adjust the output

when output voltage needs to be adjusted from the
nominal value. There are two trim options available
in the HHS60 Series.

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.
Safety Considerations
The HHS60 Series converters feature 1500 Volt DC
isolation from input to output. The input to output
resistance is greater than 10MOhm.
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 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.power-
one.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.
Figure 17. HHS60 Series Positive Trim Schematic
The equations below determine the trim resistor
value required to achieve a ∆V change in the output
voltage.

Rtrim-dn = (-------- - 2) kΩ
∆%
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:
Vo*(100+∆%) (100+2*∆%)
Rtrim-up = (-------------------- - ------------------) kΩ
1.225*∆%
∆%
•
If the voltage source feeding the module is SELV
or TNV-2, the output of the converter may be
grounded or ungrounded.
where ∆V% is the output voltage change expressed
in percent of the nominal output voltage, Vout.
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 ELV,
the output of the converter may be considered
SELV only if the output is grounded per the
requirements of the standard.
2. 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.
•
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
3. 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

Thermal Considerations
The HHS60 Series converters are designed for
natural or forced convection cooling. The maximum
allowable output current of the converters is
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 long-
term operation of the converters.

Note: Measure input reflected-ripple current with a simulated
inductance (Ltest) of 12 µH. Capacitors offset possible battery
impedance. Measure current as shown above
The graphs in Figures 5 thru 8 show the maximum

and forced convection. (longitudinal airflow direction,
