Description

The MAX682/MAX683/MAX684 charge-pump regulators generate 5V from a 2.7V to 5.5V input. They are specifically designed to serve as high-efficiency auxiliary supplies in applications that demand a compact design. The MAX682, MAX683, and MAX684 deliver 250mA, 100mA, and 50mA output current, respectively.

These complete 5V regulators MAX682 require only one resistor and three external capacitors-no inductors are needed. High switching frequencies (externally adjustable up to 2MHz) and a unique regulation scheme allow the use of capacitors as small as 1F per 100mA of output current. The MAX683/MAX684 are offered in a spacesaving 8-pin MAX package that is only 1.1mm high, while the MAX682 is available in an 8-pin SO.
