Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500 KHz.

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. DC / DC Converter -Vin -Out Cin 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.

To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 90°C. The derating curves are determined from measurements obtained in an experimental apparatus. 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. Position of air velocity probe and thermocouple 15mm / 0.6in 50mm / 2in Air Flow DUT 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 recommeded to use a good quality low Equivalent Series Resistance (ESR < 1.0[ at 100 5 MINMAX REV:0 2005/04 MSAU100 Series Mechanical Dimensions 0.3[0.01] Connecting Pin Patterns Top View ( 2.54 mm / 0.1 inch grids ) 12.7 [0.50] 8.0 [0.31] +4 8 7 6 5 ] 02 0.
