Product Summary
The MP1528DK-LF-Z 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-LF-Z uses current limited, variable frequency architecture to regulate the LED current while maintaining high efficiency. The MP1528DK-LF-Z 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.
