Linear Technology LTC1044A
The LTC1044A provides several conversion functions without using inductors. The input voltage can be inverted (VOUT = –VIN), doubled (VOUT = 2VIN), divided (VOUT = VIN/2) or multiplied (VOUT = ±nVIN). The internal oscillator can also be disabled to save power.| Part No. | LTC1044A |

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. 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.
