The LM2754SQ/NOPB is an 800mA switched capacitor flash LED driver designed for applications requiring high output current and efficiency. It operates within a wide input voltage range of 2.8V to 5.5V and can drive one to four high-power white LEDs in parallel. The device features adaptive gain settings of 1x, 1.5x, and 2x to optimize efficiency based on the LED forward voltage and current requirements. Key functionalities include a time-out protection circuit that limits flash duration to prevent damage to the LEDs, and a true shutdown feature that disconnects the output during low power states. The LM2754 also incorporates internal soft-start circuitry to limit inrush current during startup. It is packaged in a compact 24-pin WQFN format, making it suitable for space-constrained applications such as mobile phones and digital cameras. The operating temperature range is from -40¬8C to +85¬8C, ensuring reliability in various environments.
