Краткое описание:
White LED Adaptive 1.5x/1x Switched-Capacitor Current Driver
Дополнительная информация
The LM27951 is a switched-capacitor white-LED driver capable of driving up to four LEDs with 30 mA through each LED. It operates over an input voltage range from 2.8 V to 5.5 V and requires only four low-cost ceramic capacitors, utilizing a 3/2x or 1x gain transition based on LED forward voltage to maintain high efficiency without an inductor.
