    Docket ↓
    LT1509
    Power Factor and
    PWM Controller U DESCRIPTION FEATURES The LT ® 1509 is a complete solution for universal off-line
    switching power supplies utilizing active power factor
    correction. The PFC section is identical to the LT1248 PFC
    controller except the EN/SYNC pin is removed because
    PFC and PWM are synchronized internally. PFC and PWM Single Chip Solution
    Synchronized Operation up to 300kHz
    99% Power Factor over 20:1 Load Current Range
    Current Mode PWM
    Instantaneous Overvoltage Protection
    Dedicated Overvoltage Protection (OVP Pin)
    Minimal Line Current Dead Zone
    Typical 250µA Start-Up Supply Current
    Line Switching Noise Filter
    Low Quiescent Current: 13mA
    Fast 2A Peak Current Gate Drivers
    Separate Soft Start Controls ■
