Краткое описание:
White LED Adaptive 1.5X/1X Switched Capacitor Current Driver
Дополнительная информация
The LM27952 is a switched capacitor white-LED driver capable of driving up to 4 LEDs with 30mA through each LED. It features 4 tightly regulated current sinks to ensure excellent LED current and brightness matching. It operates over an input voltage range of 3.0V to 5.5V and utilizes an adaptive 1.5X/1X gain transition based on LED forward voltage to maximize efficiency.
