Datasheet	AS3492-ams.pdf

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.

2 MHz DCDC Boost converter - Small 4.7µH external coil - Very high system efficiency of 86% (DCDC and current sources combined) - Very low voltage changes on output to avoid acoustic noise on output capacitor even with PWM - Smooth startup even under low duty cycle PWM conditions.
Five Current sources up to 25mA - Low voltage compliance (150mV) - High side current source to simplify layout and thermal management of the LEDs - Automatically detect and disable failing or not used LEDs t.
