LED DRVR 4Segment 3.3V/5V 16-Pin SQFN EP T/R

This LSI is a 4 white LED driver for small LCD backlight. At the charge pump type, the number of external devices is minimized.

• 4 parallel LED driver is mounted.
• The LED current can be controlled via an external resistance.
• Maximum current is 120mA (30mA × 4).
• LED1 to LED4 can be turned on or off via an external control pin.
• The relative current accuracy among LEDs (LED1 to LED is 3%.
• Automatically transition to each mode (×1.0, ×1.5, ×2.0).
• High efficiency (90% or more at maximum) is achieved.
• Various protection functions such as output voltage protection function, current overload limiter and thermal shutdown circuit are mounted
