  • 主要特性

    • PWM peak current mode controller
    • Input operating voltage up to 75 V
    • Internal high-voltage start up regulator with 20 mA current capability
    • Current sense with programmable blanking time up to 200 ns
    • Programmable fixed frequency up to 1 MHz
    • Soft-start up with settable time
    • Soft turn off (optionally disabled)
    • Dual low-side complementary gate drivers
    • Programmable dead time from 10 to 200 ns between GATE1 and GATE2
    • Gate drivers have 1 A peak capability
    • GATE2 optionally turned off for reduced consumption
    • 80% maximum duty cycle with internal slope compensation
    • Internal pull-up resistor on CTL pin enables the optocoupler connection
    • Operating current consumption & 1.5 mA
    • Embedded protections:
      • Severe overcurrent protection with latch after 4 events
      • Delayed overload protection with automatic restart
      • Feedback disconnection (OV) protection on VC
      • Thermal shutdown
    • High efficiency topologies:
      • Flyback, forward
      • Flyback with synchronous rectification
      • Flyback with active clamp
      • Forward with active clamp
