LTC1046CS8#PBF

LTC1046 is a monolithic CMOS switched capacitor voltage converter. It plugs in for the ICL7660/ LTC1044 in 5V applications where more output current is needed. This device is optimized to provide high current capability for input voltages of 6V or less. It trades off operating voltage to get higher output current. It provides several voltage conversion functions: the input voltage can be inverted (VOUT = –VIN), divided (VOUT = VIN/2) or multiplied (VOUT = ±nVIN). It is widely used in application such as conversion of 5V to ±5V supplies, precise voltage division, VOUT = VIN/2, supply splitter, VOUT = ±VS/2 etc.
