NCP303750 Description
1 PWM PWM Control Input and Zero Current Detection Enable PWM divider resistors connected in both states when DISB# = High PWM divider resistors disconnected in both states when DISB# = Low 2 ZCD# ZCD / FCCM select input (see Table 1): ZCD# = High − Placing PWM into mid-state pulls GH and GL low without delay. There is an internal pull-up resistor to VCC on this pin when DISB# = High.
