The flyback topology is ideal for systems where the battery voltage can be either above or below the output voltage, and where multiple output voltages are required. The ML4863 uses the output voltage as the feedback control signal to the current mode variable frequency flyback controller. In addition, a synchronous rectifier control output is supplied to provide the highest possible...
