PRODUCT OVERVIEW
The MINMAX MSAU100 series is a range of 1W DC/DC converters in a SMD- Package featuring I/O-isolation of 1000VDC.The small footprint makes this
product the ideal solution for many applications where a voltage has to be isolated i.e for noise reduction, ground loop elimination, in digital interfaces or
where a converted voltage is required.
An excellent efficiency allows an operating temperature range of–40°C to +85°C. These converters are fully qualified for the higher temperature profile
used in lead-free reflow solder processes. For automated SMD production lines the product can also be supplied in tape& reel package.

Notes
1
Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2
Ripple & Noise measurement bandwidth is 0-20MHz.
3
These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules;
4
All DC/DC converters should be externally fused at the front end for protection.
5
Other input and output voltage may be available, please contact factory.
6
Specifications subject to change without notice.
however they may not meet all specifications listed.

Test Configurations
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (220uF, 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 Cout 0.33uF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load

Design & Feature Considerations
Maximum Capacitive Load
The MSAU100 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. For optimum performance we recommend 33uF maximum capacitive load.
The maximum capacitance can be found in
the 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 100 KHz) capacitor of a 2.2uF for the 5V input devices, a 1.0uF for the 12V input devices and a 0.47uF for the 24V input 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 0.47uF capacitors at the output.

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 90℃. The derating curves are determined from
measurements obtained in a test setup.
