AS3492 Datasheet (ams) - Highly Efficient 2-10 LEDs Backlight Driver

AS3492, Highly Efficient 2-10 LEDs Backlight Driver

The AS3492 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.
