DESCRIPTION
Standard Size: 2in x 1in x 0.43in (50.8mm x 25.4mm x 11mm)
The MRW20 series of DC/DC converters offers up to 20 watts of output power in
an ultra-compact 2” x 1” x 0.43” industry standard package. This series consists of
single and dual output models with ultra-wide input range, high efficiency, and no
minimum load requirements. Each model in this series is RoHS & REACH
compliant, has over current, over voltage, and short circuit protection, and has two
pin specifications available as well as optional heatsink. This series has
UL/cUL/IEC/EN62368-1 (60950-1) safety approvals and CE marking.

NOTES
1.
To indicate “A” type pinning, add –A suffix to model number. Ex. MRW20-24S05-A
To indicate heatsink, add –H suffix to model number. Ex. MRW20-24S05-H
To indicate both “A” type pinning and Heatsink, add –AH to model number. Ex. MRW20-24S05-AH
2. # for each output
3. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
4. Natural Convection is about 20LFM but is not equal to still air (0LFM).
5. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required.
Suggested Capacitors:
24V Input Models: CHEMI-CON KY Series 390µF/63V
48V Input Models: CHEMI-CON KY Series 330µF/100V
110V Input Models: CHEMI-CON KXJ Series 390µF/200V
6. Other input and output voltages may be available, please contact factory.
7. It is recommended to protect the converter by a slow blow fuse in the input supply line.
*Due to advances in technology, specifications subject to change without notice.

Advantages of Heatsink:
1. Improve heat dissipation and increase
stability/reliability of DC/DC converter at
high operating temperatures.
2. To increase operating temperature of the
DC/DC converter, please refer to derating
curve.

MRW20 SERIES
20 Watts
DC/DC Converter
Single and Dual Output
TEST SETUP
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.
TECHNICAL NOTES
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 power 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 the on/off terminal (Pin 3) during a logic low is -100µA.
Overload Protection
To provide hiccup mode protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure
overload for an unlimited duration.
Overvoltage Protection
The output overvoltage 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 overvoltage. The OVP level can be found in data sheet.
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 100KHz) capacitor of a 4.7µF for the 24V input devices, a 2.2µF for the 48V devices and a 1µF for the 110V devices.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as practicable 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
This series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up,
affecting the ramp-up and the startup time. The maximum capacitance can be found in the data sheet.
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 105ºC. The derating
curves are determined from the measurements obtained in a test setup.
