WHITE LED DRIVER General Description
Features
AP3008
The AP3008 is a 1.
2MHz PWM boost switching
regulator designed for constant-current white LED driver applications.
The AP3008 can drive a string of 2 to 3 white LEDs from a 2.
7V supply in series, ensuring uniform brightness and eliminating several ballast resistors.
The AP3008 implements a constant frequency 1.
2MHz PWM control scheme.
The high frequency PWM operation also saves board space by reducing external component sizes.
To improve efficiency, the feedback voltage is set to 95mV, which reduces the power dissipation in the current setting resistor.
· Inherently Uniform LED Current · High Efficiency up to 84% · Drives 2 ...
