n High Voltage Upgrade to ICL7660/LTC1044 The LTCВ®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 functions without using inductors. The input voltage can be
inverted (VOUT = –VIN), doubled (VOUT = 2VIN), divided
(VOUT = VIN/2) or multiplied (VOUT = В±nVIN). n Applications n n n n n Conversion of 10V to В±10V Supplies
Conversion of 5V to В±5V Supplies
Precise Voltage Division: VOUT = VIN/2 В±20ppm
Voltage Multiplication: VOUT = В±nVIN
Supply Splitter: VOUT = В±VS/2
