Lowest component count switcher solution
Selectable device current limit
Fully integrated auto-restart for short-circuit and open-loop protection
Optional self-biased supply
Frequency jittering greatly reduces EMI
Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package
Pin-out simplifies PCB heat sinking
Output overvoltage protection (OVP)
Input overvoltage line protection (OVL)
Hysteretic over-temperature protection (OTP)
Extended creepage between DRAIN pin and all other pins improves field reliability
725 V MOSFET rating for excellent surge withstand
900 V MOSFET rating series for industrial design or extra safety margin
Extremely low component count enhances reliability
Allows single-sided PCB and full SMD manufacturability
Easily meets all global energy efficiency regulations
No-load consumption <100 mW without bias winding at 265 VAC input (<10 mW with bias winding)
ON/OFF control provides constant efficiency to very light loads –ideal for mandatory CEC regulations
