PMIC - AC DC Converters, Offline SwitchersThe NCP1230D133R2G (NCP1230 for short) is a high voltage and ultra-high voltage switching integrated circuit (IC) specially developed for open and closed board systems. It was designed by ON Semiconductor to help save space, time, and cost for designers and end users. Using its integrated N-Channel MOSFET, the NCP1230 can convert AC-DC power from +12V DC to +130V DC. The NCP1230 is a great choice for applications such as industrial, telecom, and other power equipment. Its primary purpose is to provide a step-up voltage converter which minimizes the size and cost of powering higher voltage electronics. This AC-DC converter is also used in various applications such as automotive, battery chargers, point-of-load (POL) regulators, power supplies and LED ballast.The NCP1230 is powered by the input voltage so there’s no need for an additional power source. The device contains an integrated N-channel MOSFET with a maximum operating voltage of 130V. It offers an operating frequency range of up to 250kHz and an efficiency of up to 95%. The device also has an under-voltage lockout (UVLO) feature to ensure safe operation.The NCP1230 has a range of protection features such as over-voltage protection (OVP) and thermal shut-down (TSD) for safety. The device also features a soft-start feature to minimize output voltage overshoot. The device is available in two different packages, SO-8 and QFN-14.When it comes to working principles, the NCP1230 relies on a high-voltage N-channel MOSFET-based topology to convert AC-DC power. The topology consists of a transformer, rectifier and N-channel MOSFET. The transformer steps up the input voltage to the desired level. The rectifier then rectifies the high voltage output of the transformer into a DC signal. The N-channel MOSFET acts as the switching device and sends the DC signal to the output. Overall, the NCP1230 is an ideal solution for high voltage and ultra-high voltage applications such as point-of-load (POL) regulators and LED ballast. It offers space and cost savings, protection features and high efficiency. Its integrated N-channel MOSFET makes the device well suited for a wide range of applications.
