include: D programmable start/stop D less than 5-mA supply current in UVLO mode D internal start-up circuit, programmable soft-start, and power_good output. The following sections discuss in detail design considerations for creating an efficient 800-mW flyback converter with the Si9113. Refer to the application circuit from Figure 6. Start/Stop Programming The European Telecommunication Standards Institute (ETSI) requires the NT1 and the regenerator directed towards the line terminal to remain a.
