The LTC ? 1046 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 (V OUT = – V IN ), divided
(V OUT = V IN/ 2) or multiplied (V OUT = ± nV IN ).
Designed to be pin-for-pin and functionally compatible
with the ICL7660 and LTC1044, the LTC1046 provides 2.5
APPLICATIO S
times the output drive capability.
