... NCP1010, NCP1011, NCP1012, NCP1013, NCP1014 Plugging Equations 7 and 8 into Equation 6 leads to t Vds(t) u+ Vin P DSS + Vin and thus, The worse case occurs at high line, when Vin equals 370 Vdc. With ICC1 = 1.1 mA (65 kHz version), we can expect a DSS dissipation around 407 mW. If you select a higher switching frequency version, the ICC1 increases and it is likely that the DSS consumption exceeds that number ...

... NCP1010, NCP1011, NCP1012, NCP1013, NCP1014 Soft−Start The NCP101X features an internal 1.0 ms soft−start activated during the power on sequence (PON). As soon as V reaches VCC , the peak current is gradually CC OFF increased from nearly zero up to the maximum internal clamping level (e.g. 350 mA). This situation lasts 1.0 ms and further to that time period, the peak current limit is blocked to the maximum until the supply enters regulation ...
