The NCP1028P065G from ON Semiconductor is a versatile and high-performance PWM controller designed for AC-DC power supply applications. This integrated circuit offers a compact solution for power conversion and is ideal for use in a wide range of electrical devices, including adapters, offline battery chargers, auxiliary supplies, and numerous consumer electronics products.

Integrating a fixed-frequency current mode controller with a 65 kHz switching frequency, the NCP1028P065G provides a stable and efficient power supply. It incorporates a high-voltage startup circuit, which ensures reliable startup and reduces standby power consumption. The device's built-in soft-start feature minimizes stress on the power components during startup, enhancing the overall longevity and reliability of the power supply.

The NCP1028P065G is equipped with multiple protection features that safeguard the system against a variety of faults. These include overvoltage protection (OVP), overcurrent protection (OCP), and over-temperature protection (OTP), as well as short-circuit protection (SCP), which helps to prevent damage to the power supply and the load in the event of an output short circuit.

ON Semiconductor's NCP1028P065G also offers frequency jittering, which helps to reduce electromagnetic interference (EMI), thereby simplifying compliance with EMI regulations. This is particularly valuable for applications that require quiet operation and minimal interference with other electronic equipment.

The device is housed in a compact PDIP-7 package, which makes it suitable for space-constrained applications. The NCP1028P065G is designed to work with a wide range of input voltages, making it a flexible choice for global products that must operate in various power environments.

ON Semiconductor's commitment to quality ensures that the NCP1028P065G meets the highest standards of performance and reliability. Whether you are designing a new power supply or upgrading an existing one, the NCP1028P065G offers a solution that combines efficiency, versatility, and protection features in a single, integrated package.
