Switched-Capacitor Voltage Inverters
General Description
The ultra-small MAX828/MAX829 monolithic, CMOS
charge-pump inverters accept input voltages ranging
from +1.5V to +5.5V. The MAX828 operates at 12kHz,
and the MAX829 operates at 35kHz. Their high efficiency
(greater than 90% over most of the load-current range)
and low operating current (60μA for the MAX828) make
these devices ideal for both battery-powered and board-
level voltage-conversion applications.
The MAX828/MAX829 combine low quiescent current
and high efficiency. Oscillator control circuitry and four
power MOSFET switches are included on-chip.
Applications include 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.
For a similar device with logic-controlled shutdown,
Features
o 5-Pin SOT23-5 Package
o 95% Voltage Conversion Efficiency
o Inverts Input Supply Voltage
o 60μA Quiescent Current (MAX828)
o +1.5V to +5.5V Input Voltage Range
o Requires Only Two Capacitors
o 25mA Output Current
Ordering Information
refer to the MAX1719/MAX1720/MAX1721. For applica-
tions requiring more power, the MAX860 delivers up to
50mA with a voltage drop of 600mV, in a space-saving
μMAX package.
