Working Principle

The operation of the UBA2028T/N1,518 PMIC - Lighting, Ballast Controller is based on the principle of voltage regulation. The circuit tries to maintain the output voltage of the power supply to be equal to the reference voltage. While doing this, the circuit also works to minimize the current passing through the system.

The chip works as a power controller for the system. It has two inputs – a sense line and a control line. The sense line is used to monitor the output voltage of the power supply, while the control line is used to adjust the output voltage to the desired value. The input voltage and output voltage are compared and if the output voltage is below the set value, the chip adjusts the output voltage using the control line, excluding the sense line.

The chip is powered by a supply voltage, typically 5V to 15V. The operating temperature of the chip ranges from -40°C to +125°C, which makes it suitable for usage in a variety of different environment.

The UBA2028T/N1,518 is an ultra-low-cost, efficient and reliable power management integrated circuit for controlling different types of lighting systems. It is highly cost-effective, which helps to save cost in long term. The chip is highly efficient and the output voltage is accurately adjusted to the desired value. This helps in the maintenance of the desired power supply for the system, thus increasing the reliability and life expectancy of the system.
