... When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSDM311 device reduces total component count and design size and weight; while increasing efficiency, productivity, and system reliability. This device provides a basic platform that is well suited for the design of cost- effective flyback converters ...

... Start-up: At start-up, the internal high-voltage current source supplies the internal bias and charges the external Vcc capacitor, as shown in Figure 15. In the case of the FSDM311, when Vcc reaches 9V, the device starts switching and the internal high-voltage current source stops charging the capacitor. The device is in normal operation provided that Vcc does not drop below 7V ...

... SenseFET turns on. LEB 4. Protection Circuit: The FSDM311 has several protective functions, such as overload protection (OLP), over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown (TSD). Because these protection circuits are fully integrated in the IC without external components, the reliability is improved without increasing cost ...

... Burst Operation: To minimize the power dissipation in standby mode, the FSDM311 enters burst--mode operation. As the load decreases, the feedback voltage decreases. The device automatically enters burst mode when the feedback voltage drops below V this point, switching stops and the output voltages start to drop ...
