... Selection Table on Page 2, details the differences between references, mainly peak current setpoints and operating frequency. No need for an auxiliary winding: ON Semiconductor Very High Voltage Integrated Circuit technology lets you supply the IC directly from the high- -voltage DC rail. We call it Dynamic Self- -Supply (DSS). This solution simplifies the transformer design and ensures a better control of the SMPS in difficult output conditions, e ...
