TEST CONFIGURATIONS DESIGN CONSIDERATIONS TO OSCILLOSCOPE Input Source Impedance L VI(+) To maintain low noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the 100uF 2 BATTERY module. Figure 32 shows the input ripple voltage (mVp-p) Tantalum for various output models using 200 µF(2 x100uF) low VI(-) ESR tantalum capacitor (KEMET p/n: T491D107M016AS, AVX p/n: TAJD107M106R, or equivalent) in parallel with Note: Input reflected-rippl

DESIGN CONSIDERATIONS (CON.) FEATURES DESCRIPTIONS The power module should be connected to a low Remote On/Off ac-impedance input source. Highly inductive source impedances can affect the stability of the module. An The DNM/DNL series power modules have an On/Off input capacitance must be placed close to the modules pin for remote On/Off operation. Both positive and input pins to filter ripple current and ensure module negative On/Off logic options are available in the stabili

Vtrim = 0.7 − 0.1698 × (Vo − 0.7525 ) FEATURES DESCRIPTIONS (CON.) For example, to program the output voltage of a DNL Over-Temperature Protection module to 3.3 Vdc, Vtrim is calculated as follows The over-temperature protection consists of circuitry that Vtrim = 0.7 − 0.1698 × (3.3 − 0.7525 ) = 0.267V provides protection from thermal damage. If the temperature exceeds the over-temperature threshold the Vo module will shut down. The module will try to restart after shutdown.

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 Delta’s DC/DC power modules are characterized in heated ver
