LTC1044A

12V CMOS

Voltage Converter

FeaTures

DescripTion

The

LTC

1044A

is a monolithic CMOS switched-capacitor

voltage converter. It plugs in for ICL7660/LTC1044 in

applications where higher input voltage (up to 12V) is

needed. The LTC1044A provides several conversion func-

tions without using inductors. The input voltage can be

inverted (V

OUT

= –V

), doubled (V

OUT

= 2V

), divided

OUT

= V

/2) or multiplied (V

OUT

= ±nV

To optimize performance in specific applications, a boost

function is available to raise the internal oscillator frequency

by a factor of seven. Smaller external capacitors can be

used in higher frequency operation to save board space.

The internal oscillator can also be disabled to save power.

The supply current drops to 1.5µA at 5V input when the

OSC pin is tied to GND or V
