LM3519 driver equivalent, high frequency boost white led driver.
a proprietary PFM regulation architecture with switching frequencies between 2MHz to 8MHz, minimizing inductor size. Over-voltage protection circuitry and high frequency .
n LCD, White LED Backlighting on Mobile Phones n Digital Still Cameras and PDAs n General Purpose LED Lighting in Handhe.
The LM3519 drives up to 4 white LEDs with constant current to provide LCD backlighting in handheld devices. The LED current is internally set to 20mA. The series connection allows the LED current to be identical for uniform brightness and minimizes t.
