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 < 1.0[ at 100 KHz) capacitor of a 2.2uF for the 5V input devices, a 1.0uF for the 12V input devices. DC / DC Converter -Vin -Out Cin 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 1.5uF capacitors at the output. + DC Power Source -Vin +Vin Single Output DC / DC Converter -Out +Out Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0[ 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.

Copper Strip Cout Cout Scope Resistive Load Scope 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 90C. The derating curves are determined from measurements obtained in an experimental apparatus. -Out Design & Feature Considerations Maximum Capacitive Load The MAU400 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 220uF maximum capacitive load for dual outputs and 680uF capacitive load for single outputs. The maximum capacitance can be found in the data. 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. + DC Power Source + Cin +Vin DC / DC Converter -Vin +Out Load -Out MAU400 Series Mechanical Data 22.0 [0.87] Top View ( 2.54 mm / 0.1 inch grids ) Connecting Pin Patterns Single Output 0.5 [0.02] 3.5 [0.14] 21.0 [0.83] 2.54 [0.100] 3.5 [0.14] 12.5 [0.49] Dual Output 12 567 Tolerance Millimeters .X{0.25 .XX{0.25 {0.05 Pin .XXX{0.01 {0.002 Pin Connections Pin 1 2 5 6 7 Single Output +Vin -Vin -Vout No Pin +Vout Dual Output +Vin -Vin -Vout Common +Vout 0.25 [0.010] Inches .XX{0.01 2.0 [0.08] 0.50 [0.020] 7.5 [0.30] Physical Characteristics 22.0X7.5X12.5 mm 1.31*0.81*0.4 inches Non-Conductive Black Plastic 3.9g Case Size : Case Material Weight : : Units are encapsulated in a low thermal resistance molding compound which has excellent chemical resistance and electrical properties in high humidity environment and over a wide operating temperature range.
