PMIC or Power Management Ic is one of the most essential components in all electronic systems, as it is capable of providing power conversions of all sorts between AC/DC, to stabalize, to regulate and to monitor power inputs. NCP1050ST44T3G is one of the most popular PMIC products of On Semi which works as a offline switcher. It offers the feature of AC to DC conversion, as well as its superior line regulation and low THD performance.

Overview of NCP1050ST44T3G

NCP1050ST44T3G is a offline switching power converter with superior line regulation capability, low THD performance and tight line and load regulations. This product is an offline single stage flyback converter with isolated output. Its operating frequency range is from 40 kHz to 250 kHz, which provides a wide range of settings to optimize its power performance. The switching frequency is adjustable between 40kHz and 250kHz, the line regulation is only 0.2% and its peak load current can reach up to 600 mA. With these superior specs, it is an ideal solution for offline AC/DC converters. In addition, it is rated to Class B EMI in both conducted and radiated noise and offers a reliable solution against any interference.

Application fields of NCP1050ST44T3G

NCP1050ST44T3G offers a wide range of applications in various power domains. It is mainly used in AC to DC power supplies, battery chargers, portable electronic devices, switching power supplies, and power quality systems. Its superior line regulation and low Total Harmonic Distortion (THD) performance make it ideal for these applications, as it can provide cleaner power output even in more demanding situations. In addition, its low power consumption and wide input voltage range of 20V-60V make it versatile enough to be used in different scenarios.

Working Principle of NCP1050ST44T3G

In general, NCP1050ST44T3G follows the typical working principle of a flyback converter. During its operation, its internal switch is used to convert the AC input voltage into a higher DC voltage on the output side. The internal switch regulates the power transfer from the input to the output, controlling the amount of power which is transferred from the input to the output at any given time. To keep the output voltage stable, the internal feedback loop is used to adjust the duty cycle of the internal switch. This feedback loop guarantees that the output will always remain stable and that the fluctuations on the input side will only affect the power transfer, not the output voltage itself.

In addition, NCP1050ST44T3G also provides protection features to safeguard the power source and the connected load. This includes the inrush and overvoltage protection, the short circuit protection and the overload and over temperature protection. All these features guarantee that the power source and the connected load are safe from any kind of damage.

Conclusion

NCP1050ST44T3G is one of the most popular PMIC products from On Semi, and is an ideal solution for multiple power applications. It offers superior line regulation and low THD performance, which makes it suitable for applications requiring clean and stable power output. In addition, it is also protected by multiple safety features to guarantee its reliability in any situation. Together with its wide input voltage range, NCP1050ST44T3G is the perfect choice for an AC/DC converter.
