TPS61169DCKR Typical application Circuitry

TPS61169DCKR

The TPS61169 is an LED driver from Texas Instruments optimized for backlight applications. The "DCKR" in the part number TPS61169DCKR typically gives hints about the packaging and orderable options. Let's delve into the main features and functionalities of the device:

1. LED Driver Functionality: The TPS61169 primarily serves as a boost converter, but it's specialized for driving LEDs. It is particularly designed for backlighting applications, including those for single-cell battery-powered devices.

2. Input Voltage Range: The device operates within an input voltage range of 2.7V to 18V, making it compatible with a range of power sources.

3. Adjustable Output Voltage: With an integrated 27V switch, the device can support adjustable output voltages suitable for driving several LEDs in series.

4. Single Wire Interface: The TPS61169 employs a single wire EasyScale™ interface. This interface permits pulse-code modulation (PCM) brightness control and programming with just one wire.

5. Packaging: The "DCKR" suffix typically suggests that the TPS61169DCKR is housed in a small-outline SC-70 package, which is suitable for space-constrained applications.

6. High Efficiency: The TPS61169 offers high efficiency, especially important in battery-powered applications to maximize battery life.

7. Protection Features: The device integrates several protective mechanisms for safe operation:

- Overvoltage protection (OVP) to safeguard against excessive output voltages.

- Open LED protection, ensuring the device remains safe even if some LEDs in the series become open-circuit.

- Over-temperature protection (OTP) to avoid overheating.

- Soft start feature to control inrush current during startup.

8. Brightness Control: The device supports PWM (Pulse Width Modulation) brightness control, enabling dynamic adjustment of LED brightness.

9. External Components: For optimal operation, the TPS61169DCKR requires specific external components, such as an inductor, input and output capacitors, and a Schottky diode. The selection of these components has a significant influence on the device's performance and efficiency.

10. Applications: Given its specialization, the TPS61169 is suitable for:

- Backlighting in LCD displays for smartphones, tablets, and other electronic devices.

- General LED-driven illumination applications.

For an in-depth understanding, including recommended application circuits, specific operating conditions, and more, it's advisable to consult the TPS61169's datasheet directly from Texas Instruments. This datasheet provides comprehensive technical details necessary for designers and engineers working with the IC.
