具有双路 1A 高侧电流源的同步升压双 1A 闪光灯驱动器(总闪光电流为 2A) 16-DSBGA -40 to 85
General Description
The LM3560 is a 2MHz fixed frequency synchronous boost converter with two 1000 mA constant current drivers for high current white LEDs. The dual high-side current sources allow for grounded cathode LED operation and can be tied together for providing flash currents at up to 2A through a single LED.
An adaptive regulation method ensures the current for each LED remains in regulation and maximizes efficiency.
