1 / 9 page ML0308 Preliminary ______________________________________________________________________________________________________ 1/9 Rev. B, July 2005 ML0308A/B - Tiny Package, High Efficiency, White LED Driver and Step-up DC/DC Converter TYPICAL APPLICATIONS Figure 1: One-cell Li-ion to 15V Converter and White LED Driver APPLICATIONS LCD Bias Handheld Computers Battery Backup Digital Cameras FEATURES 1.2MHz Switching Frequency Furnishes the Use of Tiny Surface Mount Components High Output Voltage: Up To 16V Automatic Softstart Drives Up To Four White LEDs From 3.6V Supply DESCRIPTION The ML0308 are high efficiency, white LED driver and step-up DC/DC converters in a tiny SOT23 5-lead package. The ML0308 switches at 1.2MHz. High switching frequency permits the use of tiny, low profile inductors and capacitor to minimize footprint and cost in space-conscious portable applications. The 18V switch allows high output voltage up to 16V to be easily generated in a simple boost topology avoiding the use of costly transformers. |
