TPS92020DR Integrated Circuits (ICs)

The TPS92020DR LED driver is a 12-bit PWM LED driver from Texas Instruments (TI). It is part of the company’s TPS92001 family of products, which are designed to drive LED lights. The TPS92020DR LED driver is an integrated circuit specifically designed for driving LED lights with high efficiency for a variety of applications. It has two main features: a programmable 12-bit PWM output and a 12-bit constant current output. The device also has on-board digital to analog converters (DACs) for easy configuration and control.

The TPS92020DR LED driver is ideal for a wide range of lighting applications including industrial, commercial, residential and automotive lighting. It has a low operating voltage range of 2.7V to 15V, and a wide output voltage range of up to 25V, making it suitable for driving high power LEDs with up to 25V. It also has an integrated boost converter for higher output current capability and better efficiency. In addition, it has comprehensive protection features, such as input reverse polarity protection, over temperature protection, over load protection and over voltage protection.

The TPS92020DR LED Driver operates in either PWM or constant current mode, depending on the application. In PWM mode, the device uses pulse width modulation (PWM) with a maximummodulation frequency of 2MHz to control the LED brightness. This provides fine level control of LED brightness, allowing dimming and fading effects. In constant current mode, the device uses an internal 12-bit DAC to set the output current. This provides a simple and cost effective way to control LED brightness, as it only requires a single current setting. The device uses a one wire interface for easy control and signal communication.

The TPS92020DR LED driver is a cost effective solution for driving large numbers of LEDs. It is easily configurable and is designed for low power applications. It also has an integrated boost converter for increased efficiency. The device is RoHS compliant and is available in a 24-pin DIP package.
