It is usually used to control the brightness of LED devices when the input voltage is between 8V and 30V. By using this driver, programmable current can be applied to the LEDs to achieve good brightness control, ensuring efficient and effective lighting.

Functionality of the TPS92691QPWPQ1

This device offers multiple features that enable efficient and effective LED lighting solutions. It allows four strings of LEDs to be controlled in a range of 0.5 mA to 20 mA, meaning that multiple LED strings can be controlled in a single device. The adjustable frequency oscillator allows for a frequency range of 250 kHz to 1 MHz, enabling faster LED refresh rates. It also offers LED short-circuit protection, low output voltage reach-through and ESD protection of 8KV for the device.

TPS92691QPWPQ1 Working Principle

The TPS92691QPWPQ1 is an LED Driver IC with a wide range of applications. It works by providing a constant-current control to the LEDs by using an external resistor to control the current through the LED. This resistor is connected to the device’s CS (current sense) pin, allowing the device to control the LED’s current based on the resistor’s value. When the voltage drops below the LED’s forward voltage, the device switches off the constant current supply, protecting the LEDs from damage due to overcurrent. The device also features an adjustable frequency oscillator, allowing the user to select a frequency between 250 kHz to 1 MHz to achieve the desired LED refresh rate, while the CS pin can be utilized to control the current from 0.5 mA to 20 mA.

Conclusion

The TPS92691QPWPQ1 is an LED driver IC for PMIC applications. It facilitates efficient and effective LED lighting, allowing for precise control of current and brightness control. It comes in an 8 mm × 8 mm VQFN package and can reduce power consumption, extend the life cycle of the LEDs and produce energy savings in a wide range of LED applications including displays, signage, automotive headlights and taillights, and other lighting sources. With adjustable frequency oscillator and LED short circuit protection, it ensures superior protection for the LEDs as well as fast refresh rates for more dynamic lighting effects.
