    产品信息

    The NCP1252 controller offers everything needed to build cost effective and reliable ac-dc switching supplies dedicated to ATX power supplies or any forward application. Thanks to the use of an internally fixed timer, NCP1252 detects an output overload without relying on the auxiliary Vcc. A Brown-Out input offers protection against low input voltages and improves the converter safety. Finally, the SOIC-8 package saves PCB space and represents a solution of choice in cost sensitive project.
    • Peak current mode control
    • Adjustable switching frequency
    • Latched primary overcurrent protection with 10 ms fixed delay
    • Adjustable soft start timer
    • Auto recovery brown out detection
    • Internal 160 ns leading edge blanking
    • Frequency jittering
    • Adjustable internal ramp compensation
    • +500 mA / -800 mA Source/Sink current driver capability
    • Skip cycle operation in light/no load operation
    • SOIC-8 package
    • Extended Vcc range up to 28 V with auto recovery UVLO
