General Description
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 1F per 100mA of output
current. The MAX683/MAX684 are offered in a space-
saving 8-pin MAX package that is only 1.1mm high,
while the MAX682 is available in an 8-pin SO.
