The NCP1075STCT3G is an integrated, high-current, high-speed Power Management Integrated Circuit (PMIC) featuring Auto-Restart Control and a low standby current. It is specifically designed for lightweight, low EMI, and high accuracy AC−DC converters and offline switchers. It contains a 70 V power switch, pulse-by-pulse current limit, thermal shutdown, protection, and full functions of soft start, over-voltage protection, under-voltage protection, and brown-out protection. It provides a high efficiency solution with minimal external components and a wide input voltage range (90 - 265 VAC).

The NCP1075STCT3G is suitable for a variety of applications such as offline SMPS, CD/DVD players, LCD Monitors, LCD Televisions, Printer / Scanner Adapters, Battery Chargers, and UPS. Its compact size and excellent reliability combine to offer an ideal solution for cost-sensitive designs.

The NCP1075STCT3G features an architecture that includes two power switch stages. The primary switch is optimized for low EMI and high-speed, continuous-conduction switching. The secondary switch is optimized for low stand-by current and high efficiency. Both switches are integrated into a single integrated circuit.

The NCP1075STCT3G also features Auto-Restart Control. This is designed to provide a reliable and efficient power delivery even in case of a fault. The Auto-Restart Control monitors the output voltage and restarts the converter after the output voltage has stabilized. This ensures that the converter always operates within its specified range and provides protection against over-current, over-voltage, and under-voltage conditions.

The NCP1075STCT3G also features low stand-by current. This is designed to reduce the overall system power consumption and to improve energy efficiency. The NCP1075STCT3G features high efficiency for the converter, reducing the cost of operation and providing higher system reliability.

In addition to the features mentioned above, the NCP1075STCT3G also contains a full set of under-voltage, low power, over-voltage, and short-circuit protection. It is also capable of detecting over-temperature conditions and taking necessary protection measures. The NCP1075STCT3G is designed to operate in a temperature range of -40°C to 85°C, making it suitable for a wide range of operating environments.

In conclusion, the NCP1075STCT3G is an excellent power management IC for AC−DC converters and offline switchers. It offers high efficiency, low EMI, low power consumption, and complete protection. With its small size and excellent reliability, it provides an ideal solution for cost-sensitive designs.
