Краткое описание:
800mA Switched Capacitor Flash LED Driver with Time-Out Protection
Дополнительная информация
The LM2754 is an integrated low noise, high current switched capacitor DC/DC converter with four regulated current sinks. It is optimized for driving 1 to 4 high power white LEDs in parallel with a maximum current of 800mA. The device features adaptive 1x, 1.5x, and 2x gains to maximize efficiency and includes internal time-out circuitry to limit flash duration to 1 second for LED protection. It also features a TX input for synchronization with RF power amplifier pulses.
