The MAX682/MAX683/MAX684 charge-pump regula-

tors generate 5V from a 2.7V to 5.5V input. They are

specifically designed to serve as high-efficiency auxil-

iary 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 capacitors—no inductors are need-

ed. 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.
