The TPS92611QDGNRQ1 is a high-performance LED driver IC from Texas Instruments. It is a member of the PMIC – LED Drivers family of products. Designed for use in high-end LED lighting applications, the TPS92611QDGNRQ1 provides a wide range of features for controlling and dimming LED lighting systems.

The TPS92611QDGNRQ1 is a high-efficiency Boost mode LED driver with a wide input range of 6 V to 45 V. It includes an on-chip boost regulator, regulation logic, dimming logic, and adjustable current limit. Additionally, it offers a wide operating temperature range of -40°C to +125°C. The stability of the current flow and voltage of the LED output can be regulated with the on-chip regulation logic, which also allows for smooth dimming without flicker.

The device has two different dimming methods, either Dim to Off or Dim to GND. With Dim to Off, the brightness of the LED can be adjusted from 100% to 0% without shutting off the LED. With Dim to GND, the LED will be shut off when dimmed, and must be re-enabled when the dimming level is increased. The TPS92611QDGNRQ1 also includes a short-circuit protection feature that disables the device when the output is shorted.

The device also offers a wide range of features to control and manage energy usage. The chip includes a low-power sleep mode feature, which reduces power consumption during sleep, allowing the LED lights to be used in low-power applications. The power-saving mode helps to reduce energy usage and can be enabled and disabled via an I2C interface.

The TPS92611QDGNRQ1 also features an adjustable current limit, which can help to manage the power consumption of the LED lights. The current limit can be set to suit specific applications and can be adjusted using the I2C interface. The device also includes a thermal protection feature, which shuts off the device to protect against excessive temperatures.

The TPS92611QDGNRQ1 is an ideal solution for dimmable LED lighting applications. With its wide input range, the device can be used for a variety of high-end LED lighting applications. The on-chip boost regulator, dimming logic, and adjustable current limit features make it easy to set up and control LED lighting systems. The low-power sleep mode and adjustable current limit enable the device to be used in applications with low energy consumption. The thermal protection feature ensures that the device is protected against excessive temperatures.
