The DHW50 series is the latest generation of high performance DC/DC converters
setting a new standard concerning power density. These converters offer 50 Watts of
continuous output power in a 2.0” x 1.0” x 0.43” encapsulated, shielded metal package.
All models have a 2:1 wide input voltage range and a precisely regulated single output.
Advanced circuit topology provides a very high efficiency up to 92% and an operating
temperature range of -40°C to +80°C. Further features include remote on/off, trimmable
output voltage, under voltage lockout as well as over load, over voltage, short circuit,
and over temperature protection. These converters are RoHS compliant and are ideal
for use in battery operated equipment, instrumentation, distributed power architectures
in communication and industrial electronics and many other space critical applications.

NOTES
1. Transient recovery time is measured to within 1% error band for a step change in output load from 75% to 100%.
2. We recommend protecting the converter by a slow blow fuse in the input supply line.
3. To order the converter with a heatsink, please add the suffix “HS” to the model number. (Ex: DHW24S12-50HS)
4. Do not exceed maximum power specification when adjusting the output voltage.
5. The DHW50 series can meet EN61000-4-4 & EN61000-4-5 by adding a capacitor across the input pins. Capacitor: 220uF/100V
6. Other input and output voltages may be available; please call factory for ordering details.

OUTPUT VOLTAGE ADJUSTMENT
Output voltage trim allows the user to increase or decrease the output voltage of a module. This is accomplished by connecting an
external resistor between the Trim pin and either the +Vout or –Vout pins. With an external resistor between the Trim and –Vout pins,
the output voltage increases. With an external resistor between the Trim and +Vout pins, the output voltage set-point decreases.

Test Program Used and Operation Description
Emission Test: Set the EUT under full resistor load.
Immunity Tests: Connected a resistor load to DC output port of EUT to make EUT have maximum power consumption and a
multimeter was used to monitor voltage of output.
Primary Clock Frequencies of Internal Source
The highest frequency generated or used within the EUT or on which the EUT operates or tunes is below 108MHz, provided by factory,
for detailed internal source, please refer to manufacturers specifications.

TEST SETUP
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an inductor Lin (4.7µH) and Cin (220µF, ESR < 1.0Ω at 100 KHz) to simulate
source impedance. Capacitor Cin offsets possible battery impedance. Current ripple is measured at the input terminals of the
module. Measurement bandwidth is 0-500 KHz.
Peak-to-Peak Output Noise Measurement Test
Use a 1µF ceramic capacitor and a 10µF tantalum capacitor. Scope measurement should be made by using a BNC socket,
measurement bandwidth is 0-20MHz. Position the load between 50mm and 75mm from the DC/DC converter.
DESIGN & FEATURE CONSIDERATIONS
Remote On/Off
Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin and off during a logic low.
To turn the module on and off, the user must supply a switch to control the voltage between the on/off terminal and the –Vin
terminal. The switch can be an open collector or equivalent. A logic low is 0V to 1.2V. A logic high is 3.5V to 12V. The
maximum sink current at on/off terminal (Pin 3) during a logic low is -100µA.
Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can
endure overload for an unlimited duration.
Over Voltage Protection
The output over voltage clamp consists of control circuitry which is independent of the primary regulation loop that monitors
the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop. This
provides a redundant voltage control that reduces the risk of output over voltage. The OVP level can be found in the model
selection table.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as possible across the load will give the best ripple and noise performance.
To reduce output ripple, it is recommended to use 4.7µF capacitors at the output.

Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect
the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at
the input to ensure startup.
A Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality
low Equivalent Series Resistance (ESR < 1.0Ω at 100KHz) capacitor of a 10µF for the 24V and 48V devices.
Maximum Capacitive Load
The DHW50 series has a limitation of maximum connected capacitance on the output. The power module may be operated
in current limiting mode during start-up, affecting the ramp-up and the start-up time. The maximum capacitance can be found
in the model selection table.
Thermal Considerations
Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module, and board
spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case
temperature must be kept below 105°C. The derating curves are determined from measurements obtained in a test setup.
