PRODUCT OVERVIEW
The MSCW01 series is a family of compact 1W dc/dc-converters with wide 2:1 input voltage ranges and tightly regulated output voltages.
They work with high efficiency over the full load range and come with a remote On/Off control input.
High efficiency to 82% allows operating temperatures up to +75°C without power derating. The very small footprint of these converters make them an ideal
solution for many space critical applications in communication equipment, instrumentation and many other battery operated applications.

Test Setup
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a 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.

Technical Notes
Remote On/Off
Negative logic remote on/off turns the module off during a logic high voltage on the remote on/off pin, and on 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 high is 2~4mA current applied via 1Kohm resistor. A logic low is open circuit or high impedance.
Maximum Capacitive Load
The MSCW01 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.
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 commended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω
at 100 KHz) capacitor of a 8.2μF for the 5V input device, a 3.3μF for the 12V input devices and a 1.5μF 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 3.3μF 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 95℃. The derating curves are determined from
measurements obtained in a test setup.
