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.

♦ Ultra-Small: 1µF Capacitors per 100mA of Output

Current

♦ No Inductors Required

♦ 1.1mm Height in µMAX Package (MAX683/MAX684)

♦ Up to 250mA Output Current (MAX682)

♦ Regulated ±4% Output Voltage

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.

♦ 50kHz to 2MHz Adjustable Switching Frequency

♦ 2.7V to 5.5V Input Voltage

♦ 100µA Quiescent Current in Pulse-Skipping Mode

♦ 0.1µA Shutdown Current
