    nn TSSOP Package with High-Voltage Spacing The LTВ®8315 is a high voltage flyback converter with integrated 630V/300mA switch. No opto-isolator is needed for
    regulation. The device samples the output voltage from the
    isolated flyback waveform appearing across a third winding on the transformer. Quasi-resonant boundary mode
    operation improves load regulation, reduces transformer
    size, and maintains high efficiency. nn Applications At start-up, the LT8315 charges its INTVCC capacitor via a
    current source attached to the DRAIN pin. During normal
    operation, the current source turns off and the device
    draws its power from a third winding on the transformer. Isolated Telecom, Automotive, Industrial, Medical
