UCC28730DR Integrated Circuits (ICs)

The UCC28730DR PMIC (Power Management IC) is a high-efficiency, cost-effective single-phase AC-DC converting component designed for offline applications. It is designed to provide up to 95% efficiency over a wide range of power levels and can be used for high power self-regulating systems such as motor speed controls, solar inverters and power conditioning systems. The UCC28730DR can be implemented in both isolated and non-isolated applications.

The UCC28730DR PMIC includes an AC-DC converter, an offline switch, and a voltage regulator. The converter is responsible for converting the input AC voltage of 110V/230V AC to 12V/24V DC. The offline switch is used to control the input voltage. When the voltage drops, the offline switch detects the change and shuts off the power supply. This helps to prevent damage to the system due to overvoltage and overcurrent. The voltage regulator is used to ensure that the output voltage is within a safe range. It also helps to reduce inrush currents and maintains output voltage at a constant level.

The UCC28730DR PMIC is designed to reduce power loss and increase efficiency. To achieve this goal, it uses an innovative technology called Sweep Frequency Technology (SFT). SFT is a type of pulse width modulation (PWM) control, which utilizes the switching frequency of the converter to automatically adjust the output voltage as the line voltage increases from a minimum to a maximum. As a result, the converter is able to switch faster, enabling it to provide high-efficiency operation. Additionally, the SFT also allows for various power-saving modes such as light load operation and lower standby power.

The UCC28730DR PMIC is also designed to reduce electromagnetic interference (EMI). It uses an integrated voltage line filter that helps reduce electromagnetic interference. Additionally, it includes an internal shutdown protection which protects the system from power surges, overvoltage, and overcurrent. Other features include a current limit protection, a temperature shutdown, and a circuit protection that prevents excessive current from flowing through the load.

The UCC28730DR PMIC is a highly versatile and efficient power management IC that is designed to provide reliability and maximum performance in a variety of applications. It is suitable for a wide range of power levels and is designed for offline applications. With its high-efficiency and innovative SFT technology, it is an ideal solution for those that need a reliable and cost-effective power solution.
