Lighting and ballast controllers play an important role in regulating the amount of voltage and current supplied to lights or ballast in order to increase their efficiency, safety and lifespan.The UBA2211BT/N1,518 from UBEC is a highly efficient off-line AC/DC PWM Controller that provides a wide range of application possibilities for the lighting and ballast industry. It is the perfect solution for low-cost AC/DC applications like LED drivers, induction lamps, HID lamps, etc.

The UBA2211BT/N1,518 is designed as a self-oscillating, pulse-width-modulated controller. It offers adjustable power up to 36W and its wide coverage of voltage input range (85-265V AC), allows it to operate in most applications around the world. The controller also provides a robust protection features such as Soft-start and Over Temperature Protection.

The switching frequency of the Controller is designed to be switchable between 25kHz and 100kHz.Lower switching frequencies help to reduce switching losses, thus saving energy and increasing the overall efficiency. In addition, the current mode control provides excellent load and line regulations as well as excellent reliability, allowing the UBA2211BT/N1,518 to take load from 85 W up to 36 W.

The IC is also designed to provide a critical shutdown in order to reduce the power consumption in stand-by mode. This is important to save energy and increase the operational life of the device. In addition, the UBA2211BT/N1,518 has a precise dimming function that allows for brightness adjustment of up to 10%. This precise dimming feature allows for precise fan speed control with no audible noise.

The UBA2211BT/N1,518 is well suited for a variety of lighting and ballast applications such as LED driver, induction lamps, and HID lamps, where precise control and high efficiency are required. It is the best solution for low cost applications that require precise control of power, efficiency, and reliability. The device is available in SIP-7 (Dual in-line) packages for easy installation and compatibility with existing systems.

The main advantage of the UBA2211BT/N1,518 is its simplicity: no external components are needed, making it a very cost-effective solution. Furthermore, its wide range of voltage input range, precise dimming and protection features, and high efficiency make it the perfect choice for a variety of lighting and ballast applications.

The working principle of the UBA2211BT/N1,518 is based on the switching action of the transistor. The transistor acts as a switch and it is the main component of the controller. The transistor is turned on and off at a rate determined by the user. This switching of the transistor is what allows power to be regulated and the current or voltage to be adjusted. The speed of the switching is set by the user and the switching frequency of the controller is adjustable up to 100kHz. The voltage or current is then adjusted using the dimming function for precise control of the power supplied.

The UBA2211BT/N1,518 is a highly efficient and reliable AC/DC controller from UBEC that is well suited for a range of lighting and ballast applications. Its wide range of voltage input, precise dimming and protection features, and high efficiency make it the perfect solution for low-cost applications.
