Product Summary

The MP1528DK is a step-up converter designed for driving up to nine (9) series White LEDs (LED) from a single cell Lithium-Ion battery. It regulates the LED current and includes an analog input for varying the LED brightness. The MP1528DK uses current limited, variable frequency architecture to regulate the LED current while maintaining high efficiency. The MP1528DK is available in an 8 pin MSOP and a tiny 6 pin 3mm x 3mm QFN packages. Its applications include Handheld Computers, PDAs, PDA Phones, Digital and Video Cameras and Small LCD Displays.
