PMIC - LED Drivers

The LP8556SQX-E08/NOPB is the newest generation of LED Drivers from Texas Instruments. It is a powerful, efficient and low-power device that can be used in a variety of applications. The LP8556SQX-E08/NOPB is a synchronous rectified boost step-up converter. It is designed to drive ultra-high-brightness LEDs from a 2.5V to 16V input. The LP8556SQX-E08/NOPB has been designed to reduce energy losses by using a synchronous rectification instead of an internal Schottky diode. It also offers high efficiency, wide range of output power, and programmable output current. It is able to drive up to 13 LEDs in series with no external components required, making it suitable for lighting applications.

Applications

The LP8556SQX-E08/NOPB is a cost-effective, reliable solution for driving all types of LED displays, such as LCDs, OLEDs and Full-Color LED displays. Additionally, it can be used in automotive and industrial applications, home electronics, and any other application where high-brightness LEDs are used.

Working Principle

The LP8556SQX-E08/NOPB uses a synchronous rectified boost step-up converter with a wide range of adjustability. It consists of two main components: a synchronous rectified boost inductor and a current mode controller. The inductor is designed to charge up when the current flowing through it increases, and the controller converts the signal into a step-up voltage. This voltage is then sent to the LED, which is then illuminated by the converted electrical energy.

Benefits

The LP8556SQX-E08/NOPB offers a wide range of benefits from its efficient design. It features low switching losses, and its synchronous rectification offers higher efficiency compared to other step-up converters. It also features an adjustable output current of up to 16V, with fast response time, making it suitable for applications where precise output current is needed. Additionally, it offers wide input voltage compatibility, with an input range of 2.5V to 16V. Finally, it is designed to be flexible, with programmable output current, setting the current modulation range in increments of 0.02A.

Conclusion

The LP8556SQX-E08/NOPB is an advanced, efficient and low-power LED driver designed for a wide variety of applications. It offers efficient synchronous rectification with adjustable output current, wide input voltage compatibility, and fast response time. The LP8556SQX-E08/NOPB is an ideal choice for driving high-brightness LEDs in LCDs, OLEDs, and Full-Color LED displays.
