TPS61183RTJR Integrated Circuits (ICs)

PMIC LED drivers provide a way to control LED light sources in various applications. TPS61183RTJR is a high-efficiency, high-density LED driver that enables up to 8 LEDs in series, and can be used in a wide range of applications, including those listed below:

• Automotive exterior lighting
• Automotive interior lighting
• Backlight illumination systems
• Industrial lighting
• Home lighting
• Traffic signs and signals

The TPS61183RTJR is a one-channel, fixed frequency, step-down constant-current (CC) LED driver, specially designed for solutions that require the highest efficiency. The device can support up to 8 LEDs in series and offers a wide range of output current levels, making it suitable for a multitude of LED lighting applications. The device can be enabled via a logic level signal and features built-in short-circuit protection. It also supports thermal shutdown, open-LED protection and overcurrent protection.

The TPS61183RTJR operates from an input voltage range of 4.5V - 24V. The device can operate in two different modes. In DC mode, the LED is driven directly with the input voltage. In CC mode, the LED is driven with a constant current, which is set by an external resistor. The duty cycle of the output current is set by the internal FlexEQ loop. This reduces the number of external components and allows the LED current to be easily adjusted.

The device features an integrated average current monitoring (ACM) circuit which can be used to detect an open-LED fault. This prevents the LED from being subjected to too much current, which may cause damage. The device also features built-in hysteretic thermal shutdown, which protects the device from being subjected to too much thermal stress.

The TPS61183RTJR is an ideal choice for LED lighting applications that require high efficiency and high-density LED control. The wide range of current levels, the built-in protection features, and the ability to operate in DC and CC mode make this device suitable for a wide range of applications.
