Description
The HHS04Z52 is a DC-DC converter that operates over an input voltage range of 36VDC to 75VDC and provides
regulated 52.5V output rated up to 3.8 amps (200 watts) of continuous output current. The output is fully isolated
from the input, which allows a positive or negative output voltage configuration.
This open-frame module is constructed with a two-board approach. The power devices are connected to an
Insulated Metal Substrate (IMS) baseplate which provides a very low thermal impedance and ability to add a heat
sink. A separate PCB is populated with the control circuitry and is physically isolated from the hotter IMS board.
This approach allows for lower component temperatures, hence increasing reliability. The standard feature set
includes remote on/off, remote sensing, UVLO, OTP, OVP, output trim and a dedicated pin that connects to the
baseplate.

Once the output current is brought back into its
specified range, the converter automatically exits the
hiccup mode and continues normal operation.
9.4 Ripple and Noise
To improve accuracy and repeatability of ripple and
noise measurements, Power-One utilizes the test
setup shown in Figure 4.
9.6 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 6 shows operation of the converter under an
overvoltage condition.

Figure 4. Output Ripple & Noise Measurement Test Setup
A BNC connector is used for the measurements to
eliminate noise pickup associated with long ground
leads of conventional scope probes. The connector,
a 0.1µF ceramic and a 10µF tantalum capacitors,
and the load are located 2-3” away from the
converter.
9.5 Overcurrent Protection
To provide protection from an output overload or
short-circuit condition, the HHS04Z52 is equipped
with current-limiting circuitry and can endure the fault
condition for an unlimited duration. At the point of
current-limit inception, the converter goes into the
hiccup mode, causing the output current to be limited
both in peak and duration. Because of a lower duty
cycle, the RMS value of output current is also low.
Figure 6. Output Voltage of an HHS04Z52 Under a Forced
Overvoltage Condition. Vin=75V, No Load, Co=220µF
10. Feature Descriptions
10.1 ON/OFF
The ON/OFF (#5) pin in the HHS04Z52 converter is
referenced to the –Vin (#1) pin (see Figure 8).
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. (Consult factory for
availability of this option)
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.

Output Shorted and Vin=36V. Scale is 5A Per Division

HHS04Z52 DC-DC Converter Data Sheet
48V Input, 52.5V @ 3.8A Half-Brick Converter
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.
Note:
If the ON/OFF pin is not used, it can be left floating (positive logic),
or connected to the -Vin pin (negative logic).
10.2 Remote Sense
The HHS04Z52 converter has 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 the Figure 7.
Figure 7. HHS04Z52 Converter Trim Schematic
The equations below determine the trim resistor value
required to achieve a ∆V change in the output
voltage.

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

directly at the output of the converter and the –Sense

where ∆V% is the output voltage change expressed in

If sense pins are not connected to load, or the
respective output pins, the converter will not be
damaged, but may not met the output voltage
regulation specifications.
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.
10.3 Output Voltage Trim
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.
The trim feature allows the user to adjust the output
voltage from its nominal value.
The HHS04Z52 trims up with a resistor from the Trim
(# 7) pin to the +Sense (# 80) pin and trims down
with a resistor from the Trim pin to the –Sense (# 6)
pin as shown in the Figure 7.
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 increase
shall not exceed the limits defined in section 6 above.
4. Either Rup or Rdown should be used to adjust the output
voltage according to the equations above. If both Rup and
Rdown are used simultaneously, they will form a resistive
divider and the equations above will not apply.

A minimum of a 68µF electrolytic

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.
For output decoupling we recommend to use a 10µF
low ESR tantalum (AVX TPSC106M025R0500 is
used in Power-One test setup) and a 0.1µF ceramic
capacitor. Note that the capacitors do not substitute
the filtering required by the load.
11.2 Thermal Considerations
The HHS04Z52 converters are designed for both
natural and forced convection cooling.
The
The HHS04Z52 converter has no internal fuse. An
external fuse must be provided to protect the system
from catastrophic failure, as illustrated in figure 8.
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.
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 115°C to ensure reliable long-
term operation of the converters. Contact Power-
One for the complete list of the derating criteria.

In order for the output of the HHS04Z52 converter to
