LM3697 driver equivalent, high-efficiency three-string white led driver.
*1 Drives three parallel high-voltage led strings for display and keypad lighting
* High-voltage strings capable of up to 40-V output voltage and up to 90% effici.
* Power source for smart phone illumination
* Display, keypad, and indicator illumination
VIN = 2.7V to 5.5V VI.
The LM3697 11-bit LED driver provides highperformance backlight dimming for 1, 2, or 3 series LED strings while delivering up to 90% efficiency. The boost converter with integrated 1-A, 40-V MOSFET automatically adjusts to LED forward voltage to mini.
