+0
WHITE LED DRIVER
General Description
Features
The +0 is a 1.3MHz PWM boost switching regu-
- Inherently Uniform LED Current lator designed for constant-current white LED driver
- High Efficiency up to 84% applications.
- Drives up to 4 LEDs from a 3.2V Supply or 6
The +0 can drive a string of up to 4 white LEDs
- from a 3.2V supply or 6 white LEDs from a 5V supply in series, ensuring uniform brightness and eliminating several ballast resistors. The +0 implements a
- - constant frequency 1.3MHz PWM control scheme.
- LEDs from a 5V Supply 1.3MHz PWM Operation Frequency Requires Only 0.22µF Output Capacitor Shutdown Current: < 1µA Built-in Output Overvoltage...
