It is part of Texas Instruments’ suite of LED controllers and drivers, and the TPS92023DR LED driver offers PWM LED dimming control, adjustable boost output voltage and current sense input, allowing for improved LED light output control. The TPS92023DR LED driver is configurable specifically for dimming applications and offers maximum setup flexibility while reducing the system Design Load. It is also capable of driving up to 8 LEDs in a linear configuration.

Application field

The TPS92023DR LED driver is designed to be used in applications that require LED lighting, such as automotive lighting, general illumination, and other LED lighting applications. It has the ability to dim LED lights by controlling the LED output current, thus reducing the LED light output and saving energy. In addition, it can also be used for controlling and dimming LED lights in other applications such as digital signage and projection displays.

Working Principle

The TPS92023DR LED driver uses a constant current drive circuit. This is done by controlling the voltage on the drain of a PMOS transistor. The adjustment of the voltage from the source of this transistor sets the output current of the driver. The current of the output is set by the resistor connected between the LEDs and the drain of the PMOS transistor. The output current can also be adjusted by changing the voltage on the driver’s FB pin. In addition, the TPS92023DR LED driver can also be used to control external MOSFETs to dim the LED lighting.

The TPS92023DR LED driver features Cycle-by-Cycle Current Limiting, Undervoltage Lockout, and Line Feed-forward as protection from over current and over-voltage conditions. It also has a Windowing Comparator, allowing for fixed dimming intervals that help avoid LED flickering. The LED Driver also offers an adjustable slope compensation to reduce high frequency LED flickering and improve LED dimming.

The TPS92023DR LED Driver has the advantage of being flexible and cost effective. With its wide input voltage range of 4.5V to 24V, it can be used with a wide range of applications. It is also designed to be a low-cost solution while offering high level performance and excellent protection features.

The TPS92023DR LED driver is a great solution for controlling and dimming LED lights in a wide range of applications. It offers a wide range of features that help reduce energy costs and improve performance. With its wide input voltage range and adjustable output current, the TPS92023DR LED driver is a great way to achieve optimal LED performance.
