Using simple ON\/OFF control instead of PWM, it eliminates the need for loop compensation. Self-biasing eliminates the bias winding. Auto-restart protection limits output power during fault conditions. The SMD-8 (GN suffix) package enables surface-mount assembly.","working_principle":"The TNY268 operates with ON\/OFF control. The controller enables or disables switching cycles to regulate output. During normal operation, the EN pin (via optocoupler) controls cycle-by-cycle switching. When EN is HIGH, switching is enabled; when LOW, switching is skipped. The 700V MOSFET switches the drain current, and the internal controller is self-powered from the DRAIN pin during startup.","pin_description":"
