General Description
The MAX1606 is a step-up DC-DC converter that contains a 0.5A internal power switch and a 0.5A output isolation switch in an 8-pin µMAX package. The IC operates from a 2.4V to 5.5V supply voltage but can boost battery voltages as low as 0.8V up to 28V.

Features
♦ Adjustable Output Voltage up to 28V
♦ 20mA at 20V from a Single Li+ Battery
♦ True Shutdown (Output Disconnected from Input)
♦ Output Short-Circuit Protection
♦ 88% Efficiency
♦ Up to 500kHz Switching Frequency
♦ Selectable Inductor Current Limit (125mA, 250mA, or 500mA)
♦ 0.1µA Shutdown Current
♦ 8-Pin µMAX Package
