Краткое описание:
Synchronous Boost Converter with 500 mA High Side LED Driver and Dual-Mode Control Interface
Дополнительная информация
The LM3555 is a 2-MHz fixed-frequency, current-mode synchronous boost converter designed to drive either a single flash LED at 500 mA or two series flash LEDs at 400 mA. It features a high-voltage current source that allows for grounded cathode LED operation. The device supports a dual-mode control interface (General Purpose or I2C) and includes eight protection features such as overvoltage protection and broken inductor detection.
