RT4526 Asynchronous Boost LED Driver

The RT4526 is a high frequency, asynchronous boost converter. This converter can support White LEDs for backlighting and OLED power application, and the internal soft start function can reduce the inrush current. The device operates with 1MHz fixed switching frequency to allow small external compone.
