YB1518 Rev1.3 YB1518
Step-up DC-DC Converter White LED Driver
Description Features
The YB1518 is a step-up DC-DC converter; Built-in internal switch
operates as current source to drive up to 6 2.7V to 7V input range
white LEDs(VIN at 3.0V) or 8 LEDs(VIN at
3.5V) or 9 LEDs(VIN at 3.5V) in series. <1uA shutdown current
Series connecting of the LEDs provides PWM dimming control 100Hz to 1KHz
identical LED currents resulting in uniform Analog dimming control
brightness and eliminating the need for
