Product Details

Evaluation circuit EVAL-ADPL21210-AZ is a 2.1MHz, SOT-23 DC/DC converter featuring the ADPL21210. The Boost Circuit is designed to convert a 5V input to a 12V output at 300mA maximum load. The EVALADPL21210- AZ is designed to demonstrate the soft-start feature, advantages of the 2.1MHz switching frequency, the internal 2.1MHz/1.1A switch, wide input voltage range and small circuit size. The EVAL-ADPL21210-AZ is intended for space-conscious applications such as digital cameras, cellular phones, palmtop computers, and liquid crystal display (LCD) displays. The 2.1MHz switching frequency, 1.1A integrated switch, small circuit size, and low All registered trademarks and trademarks are the property of their respective owners. component count make the ADPL21210 suitable for use in many other applications, such as PC cards, miniature disk drives, variable digital subscriber line (xDSL) power supplies, flash memory products, and local 5V or 12V supplies.
