LM3432BSQX/NOPB is a low-power LED Driver belonging to the PMIC - LED Drivers category. Integrated with an ultraviolet LED driver, current matching external resistor, LED current adjustment pin, and I2C interface communication interface, this product provides a complete solution for driving white LED. It features up to 10 LEDs current sink and can be used in applications with low power requirements, such as smart phones and tablet PCs.The operating principle of the LM3432BSQX/NOPB is based on the control of two N-channel MOSFET switches by two control signals from the I2C to regulate the flow of current in the LED string. By setting the proportion of switched current with two N-channel MOSFET switches, the current through the LED string can be adjusted from 0A to a maximum current set by an external resistor.The LM3432BSQX/NOPB is an ideal LED driver solution for applications requiring low operating current, such as smart phones and tablet PCs. The device offers a wide range of features including fast switching time, low noise and low operating current to enable designers to build power-efficient LED driver systems.The LM3432BSQX/NOPB is the only device of its type that offers both P-Channel and N-Channel MOSFET control. This allows the device to not only drive forward current through LEDs but also reverse current to achieve both High-power and low-power LED driver applications. In addition, the LM3432BSQX/NOPB features an integrated UV LED driver, current matching external resistor, LED current adjustment pin, and I2C interface for communication. The integrated UV LED driver enables designer to quickly create UV LED light source circuits, while the adjustable current control pin is ideal for dimming applications. The LM3432BSQX/NOPB is designed witha high efficiency circuit, which significantly reduces power consumption. Its low current operation and high voltage operation also helps to extend battery life. Furthermore, the device is designed with a low start-up-voltage and high efficiency to reduce the pull-in current. All of these features enables designers to build a power efficient LED driver system.In conclusion, the LM3432BSQX/NOPB is an ideal LED driver solution for applications requiring low operating current in Smartphone and Tablet PC applications. It is integrated with an UV LED driver, current matching external resistor, LED current adjustment pin and a I2C interface communication interface, which enables designers to build an efficient LED driver system.
