♦ 5-Pin SOT23-5 Package

The ultra-small MAX870/MAX871 monolithic, CMOS

charge-pump inverters accept input voltages ranging

from +1.4V to +5.5V. The MAX870 operates at 125kHz,

and the MAX871 operates at 500kHz. Their high efficien-

c y (90%) a nd low op e ra ting c urre nt (0.7mA for the

MAX870) make these devices ideal for both battery-pow-

ered and board-level voltage-conversion applications.

♦ 99% Voltage Conversion Efficiency

♦ Invert Input Supply Voltage

♦ 0.7mA Quiescent Current (MAX870)

♦ +1.4V to +5.5V Input Voltage Range

♦ Require Only Two Capacitors

♦ 25mA Output Current

Oscillator control circuitry and four power MOSFET

s witc he s a re inc lud e d on-c hip . A typ ic a l MAX870/

MAX871 application is generating a -5V supply from a

+5V logic supply to power analog circuitry. Both parts

come in a 5-pin SOT23-5 package and can deliver 25mA

with a voltage drop of 500mV.

♦ Shutdown Control

For applications requiring more power, the MAX860

delivers up to 50mA with a voltage drop of 600mV, in a

space-saving µMAX package.
