NCP1250ASN100T1G Application field and Working Principle

NCP1250ASN100T1G is a PMIC - AC DC Converters, Offline Switchers designed by ON Semiconductor. This solution has been widely used in various applications including power conversion, monitoring and control. It is suitable for many different types of application needs, from general lighting and telecom equipment to data centers and industrial equipment.

NCP1250ASN100T1G is an AC/DC converter with a wide input voltage range of 3V to 42V and an output voltage range of 0V to 18V. It also features separate regulation for positive and negative output. It provides an output power of up to 1kW, with efficiency up to 90%. This device also features a full protection suite, which includes overvoltage protection, overcurrent protection and short-circuit protection.

In terms of working principle, NCP1250ASN100T1G consists of two power circuits: the primary circuit and the secondary circuit. The primary circuit converts the ac input to intermediate dc, while the secondary circuit regulates the voltage through a power control device to obtain the output voltage. The primary circuit contains a transformer, a rectifier, a filter capacitor and a freewheel diode. The transformer is used to step down the input voltage to the intermediate dc voltage, while the rectifier, made up of two diodes, converts the ac voltage to dc. The filter capacitor, which is placed at the output of the rectifier, helps to smooth out the ripple in the dc output.

The secondary circuit contains a power control device, a gate driver and a gate drive circuit. The power control device regulates the output voltage, while the gate driver is used to control the conduction of the power control device. The gate drive circuit is used to turn on and off the power control device at the proper time. This circuit works by sensing the feedback voltage at the output and controlling the gate drive circuit so that the output voltage remains constant.

Finally, NCP1250ASN100T1G features a number of safety-related features. These safety features include over-current and over-temperature protection, as well as ESD and creepage protection. Additionally, the device is also UL recognized, meaning that it has been independently tested to meet established safety standards.

In conclusion, NCP1250ASN100T1G is an ideal solution for a wide range of applications requiring high-efficiency AC/DC conversion, including general lighting and telecom equipment, data centers and industrial equipment.
