Product Overview
AN30888A and AN30888B are DC-DC controllers ideal for driving high-luminance LEDs for LED lighting. They are equipped with 2 lighting adjustment modes (PWM control and reference voltage control), and can be made compatible with boost, buck, or buck-boost voltage by changing the external components. In addition to LED lighting, they can also be used for general lighting such as LED backlights, LED flashes, LED lanterns, etc.
