The MAX1817 is a compact, high-efficiency, dual-output step-up converter for portable devices that provides both the main logic supply and the LCD bias. The device operates from an input voltage of +1.5V to +5.5V, allowing the use of 2- or 3-cell alkaline batteries, or 1-cell lithium-ion (Li+) batteries. The MAX1817’s main regulator supplies 125mA at either .
include a fast switching frequency to reduce the size of external components and a low quiescent current to maximize battery life. Both outputs can be independently shut down for improved flexibility. The MAX1817 is supplied in a compact 10-pin µMAX package. The MAX1817 evaluation kit (MAX1817EVKIT) is available to speed up design. Features o Dual Step-Up Converter in a Tiny 10-Pin µMAX Package o Main Output Up to 125mA Load Current Fixed 3.3V or Adjustable 2.5V to 5.5V Up to 88% Efficiency Internal Switch o LCD Output Up to 28V for LCD Bias Internal Switch o Input Voltage Range +1.5V to +5.5.
