... DC input voltages in the range of 12V to 250V, and supplies a regulated voltage of 9.5V to the V pin. DD UVLO – This pin can be used for enabling/disabling the HV9608 under voltage lockout input. Both the turn-on and the turn-off thresholds are independently programmable. By selecting appropriate resistor values, a corresponding voltage divider is connected to this pin ...

... Alternatively, the high voltage regulator can continuously supply bias current up to 20mA powering the gate driver and all internal circuits of HV9608. The need for a bootstrap power supply would be eliminated in this case. However, caution must be taken to maintain the HV9608 within its package power dissipation limits. ...

... This condition may cause saturation of the power transformer or excessive voltage stress at the clamp capacitor C order to prevent this condition, the HV9608 includes a volt-second clamp circuit that can be programmed to limit the maximum duty cycle of the PWM controller, which is inversely proportional to the ...
