DS_DNS04SIP06A_07172008 9 DESIGN CONSIDERA TIONS (CON.) The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can af fect the stab ility of the module.
DS_DNS04SIP06A_07172008 10 FEA TURES DESCRIPTIONS (CON.) Over-T emperature Protection The over-temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the ove r-temperature thre shold the module will shut down.
DS_DNS04SIP06A_07172008 11 The output voltage tracking f eature (Figure 40 to Figure 42) is achieved according to the different extern al connections. If the tracking feature is not used, the TRACK pin of the module can be le ft unconnecte d or tied to Vin.
DS_DNS04SIP06A_07172008 12 FEA TURE DESCRIPTIONS (CON.) Sequential St art-up Sequential start-u p (Figure 40) is implemented by placing an On/Off control circuit b etween V o PS1 and the On/Off pin of PS2.
DS_DNS04SIP06A_07172008 13 THERMAL CONSIDERA TIONS Thermal management is an importa nt part of the system design. To ensure prop er, reliable operation, suffici ent cooling of the power mod ule is needed over the entire temperature range of the modul e.
