Краткое описание:
2-MHz, 600-mA Synchronous Boost LED Flash Driver with I2C Interface
Дополнительная информация
The LM3561 is a 2-MHz fixed-frequency synchronous boost converter designed to operate as a single 600-mA constant current driver for high-current white LEDs. It features an I2C-compatible interface, high-side current source for grounded cathode operation, and multiple operating modes including Torch, Flash, and LED Indicator. The device includes safety features such as a hardware-enable (HWEN) pin, dual synchronization inputs for RF power amplifier pulse events, and thermal sensing.
