TPS61193PWPRQ1 Typical application Circuitry

TPS61193PWPRQ1 is a sophisticated LED driver tailored for backlighting of LCD panels. With its robust feature set, it's an ideal choice for driving multiple strings of LEDs.

Application Scenarios:

1. Television and monitor backlighting.

2. Industrial displays.

3. Automotive displays and dashboard lighting.

4. Large format LCD panels.

Feature Parameters:

1. Multi-channel output for driving multiple LED strings.

2. High-efficiency boost converter.

3. Wide input voltage range.

4. Integrated protection mechanisms like over-voltage and over-current protection.

Specific Application Scenario - Television and Monitor Backlighting:

1. Power Source:

The TPS61193PWPRQ1 requires an appropriate DC voltage source. For most TV and monitor applications, this would typically be a 12V or 24V source.

2. Pin Connections:

- VIN pin: This pin gets connected to the input power source, such as 12V or 24V.
- GND pin: Connect to the system's common ground.
- SW pins: These are the switching pins for the integrated boost converter. They should connect to an external inductor, which in turn connects to the positive terminal of the output capacitor and LED string.
- VOUT pins: These pins will give the output voltage for driving the LED strings. They should connect directly to the anodes of your LED strings.
- FB pin: Connects to a voltage divider to set the desired LED string voltage.
- CTRL pins: For PWM dimming control, you can input a PWM signal to these pins to control the brightness of the LEDs.

3. External Components:

For TPS61193PWPRQ1 to function optimally, a few external components are essential:
- An input capacitor close to the VIN pin for decoupling.
- An inductor connected to the SW pins.
- An output capacitor connected between VOUT and GND.

4. LED Strings Connection:

The cathodes of the LED strings should connect to the current sink pins on the TPS61193PWPRQ1. This ensures current regulation for each LED string.

Design Considerations:

1. Component Selection: It's vital to use components rated appropriately, especially for voltage and current, given the specifications of the TPS61193PWPRQ1.

2. Thermal Management: The TPS61193PWPRQ1 can generate heat, especially under heavy loads. Proper heat sinking or thermal relief might be necessary.

3. LED Matching: To maintain consistent brightness across all strings, the LEDs in each string should be closely matched in terms of forward voltage and luminous intensity.

4. Protection: While the TPS61193PWPRQ1 has integrated protection features, additional external protection, such as fuses, might be considered for added safety.

To wrap up, the TPS61193PWPRQ1 offers a versatile and efficient solution for LED backlighting applications. Always consult its datasheet and relevant application notes for a comprehensive understanding and optimized design.
