LM828

Switched Capacitor Voltage Converter

General Description

Features

n Inverts Input Supply Voltage

n SOT-23-5 Package

The LM828 CMOS charge-pump voltage converter inverts a

positive voltage in the range of +1.8V to +5.5V to the corre-

sponding negative voltage of −1.8V to −5.5V. The LM828

uses two low cost capacitors to provide up to 25 mA of out-

put current.

n 20Ω Typical Output Impedance

n 97% Typical Conversion Efficiency at 5 mA

The LM828 operates at 12 kHz switching frequency to re-

duce output resistance and voltage ripple. With an operating

current of only 40 µA (operating efficiency greater than 96%

with most loads), the LM828 provides ideal performance for

battery powered systems. The device is in a tiny SOT-23-5

package.
