PMIC - LED Drivers are electronic components designed to securely power and control LED light circuits. The UBA3070T/N1,118 belongs to this category and has a variety of features and applications. In this article, we\'ll discuss the application field and working principle of this device.

Application Field of UBA3070T/N1,118

The UBA3070T/N1,118 is a general-purpose LED driver IC that is optimized for outdoor and automotive applications. This device is specifically designed to drive up to 8 mid-current LEDs in series and can produce up to 30mA output current in each channel. It can support a wide range of operating voltages from 24V to 42V, so it can be used in a variety of applications such as lighting, signage, vehicle and mobile devices, and automotive applications.

The UBA3070T/N1,118 is an ideal solution for those applications where space is critical. It integrates sophisticated features such as dimmable and selectable boost modes, and adjustable current and thermal protection. It also has a multi-level dimming capability, so it can be used to control the brightness of LED lighting with a wide range of brightness levels. The device also provides a charge pump to generate the necessary supply voltage to drive the LEDs.

Working Principle of UBA3070T/N1,118

The UBA3070T/N1,118 is designed using a switched capacitor technique to regulate the output current. This technique allows the device to switch on and off the gate of the power MOSFETs at high frequencies. The device has two separate voltage pins for each power MOSFET, one for the source and one for the gate. When the gate voltage is lower than the source voltage, the MOSFET is switched off and the current flow is stopped. When the gate voltage is higher than the source voltage, the MOSFET is switched on and the current is allowed to flow.

The UBA3070T/N1,118 also features an adjustable current limit control input. This control input allows the device to be operated as either a constant current or constant power source. When the current limit input is connected to a voltage source, the device operates in constant power mode and the output current is fixed. When the current limit input is connected to ground, the device operates in constant current mode.

The UBA3070T/N1,118 can also be used as a dimming LED driver. This LED driver has an internal dimming control logic that allows it to be used as a dimming source for LED lighting systems. The dimming control logic is adjustable, so the brightness of the LED lights can be easily adjusted. The device also features an adjustable fault protection level, so it can be used in environments where safety is a priority.

Conclusion

The UBA3070T/N1,118 is a versatile LED driver IC that is optimized for outdoor and automotive applications. This device has a wide range of features including adjustable current and thermal protection, dimmable boost mode, and adjustable current limit control. It is ideal for applications where space is at a premium and can be used in environments where safety is a priority. Overall, the UBA3070T/N1,118 is an excellent choice for lighting, signage, vehicle and mobile devices, and automotive applications.
