Power management integrated circuits (PMICs) play an important role in power management systems, allowing users to reduce the size of their end products, to increase their energy efficiency, and to extend their battery life. One of the most common type of PMICs is AC/DC converters, which convert an AC voltage supply to a DC voltage that can be used for low-power appliances and applications. Another type is the so-called “offline switchers”, which are designed to convert the input power supply to operate on any kind of power source, be it AC or DC. The UCC28C42DG4 is one such PMIC with both AC/DC converter and offline switcher applications, featuring switching frequency up to 1.2Mhz.

The UCC28C42DG4 is a dual channel, low-voltage, PWM controller that can be used in a variety of AC/DC and offline switcher applications. The device features a 5V to 28V wide input voltage range, which makes it suitable for use in applications where the input voltage can vary over a wide range. The integrated PWM controller allows the device to maintain a stable output voltage, regardless of the input voltage, thus making it ideal for applications where the input voltage may fluctuate. The device also supports input voltages up to 700V, making it suitable for high voltage applications such as power supplies. The UCC28C42DG4 also features low voltage and high voltage circuits that protect the device from sudden voltage surges, thus ensuring its reliability.

The UCC28C42DG4 has two different types of output configurations, namely the buck and the boost. In buck mode, the power device is configured to step down the input voltage, thus providing a stable output voltage. The boost mode, on the other hand, allows the device to step up the input voltage to a higher value, thus providing a higher output voltage. In addition, the UCC28C42DG4 also provides over voltage and under voltage protection, over temperature protection, load transient protection, and over current protection. This makes the UCC28C42DG4 suitable for use in a wide variety of applications.

The UCC28C42DG4 also offers a range of switching frequencies, from 0.5Mhz to 1.2Mhz, which makes it suitable for a variety of applications. The device has a low on-resistance , making it highly efficient and allowing it to deliver high levels of power. The UCC28C42DG4 is also designed to operate over an extended temperature range, ensuring that it can handle the toughest environments. Furthermore, the UCC28C42DG4 also has an input voltage range up to 700V, making it suitable for applications that require voltages as high as 700V.

In conclusion, the UCC28C42DG4 is a feature-rich PMIC with both AC/DC converter and offline switcher applications. It features a wide input voltage range, up to 28V, and a switching frequency up to 1.2Mhz. The device also features a range of protection features, including input voltage, over temperature, and load transient protection. The UCC28C42DG4 is an ideal choice for applications such as power supplies and high voltage power distribution, where the input voltage could vary over a wide range and reliability is paramount.
