  • Description

    The NCP1028 is a high-voltage IC chip specifically designed for universal mains flyback applications, offering output power levels ranging from a few watts up to 15W. This IC chip incorporates a power MOSFET and a startup current source directly connected to the bulk capacitor. It features adjustable brown-out circuitry to prevent operation in low input voltage conditions until a sufficient level is reached. With current-mode operation and adjustable ramp compensation, the NCP1028 provides superior performance in universal mains applications. It also includes an over power protection pin for precise compensation in high input voltage conditions and optimizing the maximum output current capability. The NCP1028 is an excellent choice for standby/auxiliary offline power supplies or applications requiring higher output power levels.

    Specifications and features

    The specifications and features of the NCP1028 IC chip are as follows:

    • Built-in 700V MOSFET with typical RDS(on) of 5.8Ω at TJ = 25°C
    • Current-mode fixed frequency operation: 65kHz and 100kHz
    • Fixed peak current of 800mA
    • Skip-cycle operation at low peak currents
    • Internal current source for clean and lossless startup sequence
    • Auto-recovery output short circuit protection with timer-based detection
    • Programmable brown-out input for low input voltage detection
    • Programmable over power protection
    • Input to permanently latch off the part
    • Internal frequency jittering for improved EMI signature
    • Extended duty cycle operation up to 80% typical
    • No-load input standby power of 85mW at 265Vac
    • Loaded input power of 500mW at 230Vac
    • Pb-Free devices

    Application Scenarios

    The NCP1028 is commonly used in the following application scenarios:

    • Medium power AC-DC adapters for chargers
    • Auxiliary/standby power supplies for ATX and TVS power supplies
