AS3490, Highly Efficient 2-6 LEDs Backlight Driver
The AS3490 is an inductive highly efficient DCDC boost converter.
The DCDC converter operates at a fixed frequency of 2MHz and includes soft startup to allow easy integration into noise sensitive RF systems.
A predictable startup is guaranteed even with very low duty cycle PWM input signals.
