The LTC1046CS8#PBF is a monolithic CMOS inductor less switched capacitor Voltage Converter that plugs in for the ICL7660/LTC1044 in 5V applications where more output current is needed. The 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. The LTC1046 provides several voltage conversion functions, the input voltage can be inverted (VOUT = μVIN), divided (VOUT = VIN/2) or multiplied (VOUT = +/-nVIN). Designed to be pin-for-pin and functionally compatible with the ICL7660 and LTC1044, the LTC1046 provides 2.5 times the output drive capability. While the exact values of CIN and COUT are noncritical, good quality, low ESR capacitors such as solid tantalum are necessary to minimize voltage losses at high currents. To achieve the 0.0002% accuracy indicated, the load current should be kept below 100nA. However with a slight loss in accuracy, the load current can be increased.
