The LTC1046 is a 50mA monolithic CMOS switched capacitor voltage converter. It 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 = –VIN), 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.
Applications
- Conversion of 5V to ±5V Supplies
- Precise Voltage Division, VOUT = VIN/2
- Supply Splitter, VOUT = ±VS/2
