Overview
EUP2794 White LED Driver with 1X /1.
5X High-Efficiency Charge Pump DESCRIPTION The EUP2794 is a low noise, constant frequency charge pump that uses a dual mode load switch (1X) and fractional (1.
5X) conversion to maximize efficiency for white LED applications.
The EUP2794 delivers up to 80mA of load current and provides four regulated current sources, each capable of driving up to 20mA through white LEDs.
All LED pin currents are regulated, constant and tightly matched to achieve uniformity of brightness across the LCD backlight.
The switching frequency is 900kHz.
