DESCRIPTION
Size: 2.00 x 1.22 x 0.71 inches (50.8 x 31.0 x
18.0 mm)
The DH50 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. The DH50 series can meet EN55022 Class A with external capacitors in parallel with the input pins.
• 12Vin Models: 22µF/25V 1210 MLCC
• 24Vin Models: 3.3µF/50V 1210 MLCC
• 48Vin Models: 2.2µF/100V 1210 MLCC
4. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor: CHEMI-CON KY
330µF/100V
5. Do not exceed maximum power specifications when adjusting the output voltage.
6. To order the converter with a heatsink, please add the suffix “HS” to the model number. (Ex: DH12S12-50HS).
Due to advances in technology, specifications subject to change without notice.

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.

DESIGN CONSIDERATIONS
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.
TEST SETUP
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.
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. 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 100 KHz)
capacitor of 33µF for the 12VDC input models and a 10µF for the 24VDC and 48VDC input models.

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.
Maximum Capacitive Load
The DH50 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.
