DESCRIPTION
Size: 2in x 1in x 0.40~0.43in
(50.8mm x 25.4mm x 10.2~11mm)
The DHW40 series is the latest generation of high performance DC/DC converters setting a new
standard concerning power density. These converters offer 40 Watts of continuous output power
in a 2.0” x 1.0” x 0.4” encapsulated, shielded metal package. The DHW40 series has single and
dual output models with 4:1 ultra wide input voltage ranges of 9-36VDC and 18-75VDC.
Advanced circuit topology provides a very high efficiency up to 91% 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 overtemperature 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. Heatsink is available for models. Add “HS1” to model name for 24V model heatsink, or “HS” for other models.
2. Ripple & Noise measurement with a 1µF M/C and a 10µF T/C.
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 (0 LFM).
5. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor: 330µF/100V.
6. It is recommended to protect the converter by a slow blow fuse in the input supply line.
7. Other input and output voltages may be available, please contact factory.
8. Do not exceed maximum power specification when adjusting output voltage.
*Due to advances in technology, specifications subject to change without notice.

The advantages of adding heatsink are:
1. Improve heat dissipation and increase stability and
reliability of the DC/DC converters at high operating
temperatures.
2. To increase operating temperature of the DC/DC
converter, see derating curve.

DHW40 SERIES
40 Watts
DC/DC Power Converter
Single & Dual Outputs
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 100KHz) to simulate source impedance.
Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0500KHz.
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 4.7V to 12V. The maximum sink current at the on/off terminal (Pin 3) during a logic low is -100µA.
The maximum allowable leakage current of a switch connected to the on/off terminal (Pin 3) at logic high (2.5V to 100V) is 5µA.
Over Load Protection
To provide hiccup mode protection in a fault (output over load) 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 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 10µF for the 24V and 48V 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
The DHW40 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 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 measurements obtained in a test setup.
