TEST CONFIGURATIONS DESIGN CONSIDERATIONS TO OSCILLOSCOPE Input Source Impedance L To maintain low-noise and ripple at the input voltage, it is VI(+) critical to use low ESR capacitors at the input to the module. Figure 26 shows the input ripple voltage 3.3uF 2 100uF BATTERY Ceramic (mVp-p) for various output models using 2x100uF low Electrolytic ESR electrolytic capacitors (Rubycon P/N:50YXG100, 100uF/50V or equivalent) and 1x3.3.0 uF very low ESR VI(-) ceramic capacitors

THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. Thermal Testing Setup
