NC12S15A_01 102008 7 DESIGN CONSIDERA TIONS FEA TURES DESCRIPTIONS ENABLE (On/Off) The NC15 is a single phase and volt age mode controlled Buck topology . Block diagram of the converter is shown in Figure 23. The output can be trimm ed in the range o f 0.
NC12S15A_01 102008 8 The NC06/NC15/NC20 m odule has a trim range of 0.9V to 5.0V . The trim resistor equation for the NC6A/NC15A/ NC20A is : FEA TURES DESCRIPTIONS (CON.
NC12S15A_01 102008 9 FEA TURES DESCRIPTIONS (CON.) Output Capacit ance There is no output capacitor on the NC se ries modules. Hence, an external output capacitor is required for stable operation. For NC15 modules, a n external 6.3V/680 μ F low ESR capacitor (for example, OSCON) is required fo r stable ope ration.
NC12S15A_01 102008 10 THERMAL CONSIDERA TION Thermal management is an important part of the system design. To en sure proper, reliable operation, sufficient cooling of the po wer module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer.
