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.

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
