描述
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 require only one resistor and three external capacitorsno inductors are needed. High switching frequencies (externally adjustable up to 2MHz) and a unique regulation scheme allow the use of capacitors as small as 1µF per 100mA of output current. The MAX683/MAX684 are offered in a space-saving 8-pin µMAX package that is only 1.1mm high, while the MAX682 is available in an 8-pin SO.
