Features

 800 V avalanche-rugged power MOSFET allowing ultra wide VAC input range to be covered
 Embedded HV startup and sense-FET
 Current mode PWM controller
 Drain current limit protection (OCP)
 Wide supply voltage range: 4.5 V to 30 V
 Self-supply option allows the auxiliary winding or bias components to be removed
 Minimized system input power consumption:  Less than 10 mW @ 230 VAC in no-load condition  Less than 400 mW @ 230 VAC with 250 mW load
 Jittered switching frequency reduces the EMI filter cost:  30 kHz ± 7% (type X)  60 kHz ± 7% (type L)  120 kHz ± 7% (type H)
 Embedded .
