Краткое описание:
5-A Super-Capacitor Flash LED Driver
Дополнительная информация
The LM3550 is a low-noise, switched-capacitor DC-DC converter designed to operate as a current-limited and adjustable super-capacitor charger. It features user-selectable termination voltages and provides one adjustable constant current output up to 200 mA and one NFET controller for driving high-current LEDs in flash or torch modes. It includes an I2C-compatible interface for programming flash pulse duration and current levels.
