    TPS61194PWPRQ1 Typical application Circuitry Schematics

    The TPS61194PWPRQ1 is part of the TPS61194-Q1 series of automotive-qualified, high-efficiency, low-EMI, 4-channel LED drivers from Texas Instruments. This device features an integrated boost converter and 4-channel current regulators, which are designed to drive up to 28 LEDs per channel. It's particularly suitable for automotive infotainment display backlight applications. In a typical application circuit with the TPS61194PWPRQ1, you might include the following components: 

    1. Input and Output Capacitors: These capacitors are used to mitigate voltage ripple at the input and output, enhancing the stability and performance of the power supply. 

    2. Inductor: The inductor, together with the output capacitor, forms the output filter of your power supply. 

    3. Feedback Resistors: These resistors are part of the feedback loop that allows the TPS61194PWPRQ1 to maintain a stable output voltage. 

    4. LEDs: The TPS61194PWPRQ1 is designed to drive up to 28 LEDs per channel in a 4-channel configuration, up to a total of 112 LEDs. 

    5. Brightness Control: The TPS61194PWPRQ1 supports brightness control through both analog and digital (PWM) methods. PWM signals can be input to the CTRL1 and CTRL2 pins, while an analog voltage can be applied to the IREF pin to adjust the LED current. 

    6. Enable and Fault Pins: A pull-up resistor may be used at the EN pin to enable the device by default. The fault pin (FLT) can be utilized to communicate any fault conditions to a microcontroller or other supervisory circuit. 

    7. Protection Components: The TPS61194PWPRQ1 includes several built-in protection features, including overvoltage protection, overcurrent protection, LED short/open detection, and thermal shutdown. This is a generalized circuit description. 

    For detailed information on how to design an application circuit with this device, refer to the TPS61194PWPRQ1's datasheet and application notes provided by Texas Instruments. The exact schematic and component values will depend on your specific application requirements, so always ensure to follow the manufacturer's design guidelines.
