                      Product Overview

                      LTC1044A 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 = ±nVIN). To optimize performance in specific applications, a boost function is available to raise the internal oscillator frequency by a factor of seven. Smaller external capacitors can be used in higher frequency operation to save board space. The internal oscillator can also be disabled to save power. It is widely used in application such as conversion of 10V to ±10V supplies, conversion of 5V to ±5V supplies, precise voltage division: VOUT = VIN/2 ±20ppm, voltage multiplication: VOUT = ±nVIN, supply splitter: VOUT = ±VS/2, automotive applications, battery systems with 9V wall adapters/chargers etc.

                      • Operating supply voltage range is 1.5V to 12V
                      • Boost pin (pin 1) for higher switching frequency
                      • 97% minimum open circuit voltage conversion efficiency
                      • 95% minimum power conversion efficiency
                      • Supply current is 60μA typical at (RL = ∞, pins 1 and 7, no connection)
                      • Oscillator frequency is 5KHz minimum at (V+ = 5V)
                      • Operating temperature is -40°C to 85°C
                      • Package style is 8-lead NSOIC
