Краткое описание:
1A Switched Capacitor Flash LED Driver with I2C Compatible Interface
Дополнительная информация
The LM2759 is an integrated low-noise, high-current switched capacitor DC/DC converter with a regulated current source. It is capable of driving loads up to 1A from a single-cell Li-Ion battery using adaptive 1x, 1.5x, and 2x gains for maximum efficiency. The device features an I2C-compatible interface for programming flash pulse duration and current levels, and includes a hardware Strobe pin and a TX input pin to synchronize with RF power amplifier pulses.
