| Features |
a high−voltage startup FET which ensures a clean and loss−less startup sequence. Its current−mode control naturally provides good audio−susceptibility and inherent pulse−by−pulse control.
When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically enters the so−called skip cycle mode and provid...
