LTC1044Switched Capacitor Voltage Converter | Voltage Regulators - DC DC Switching Regulators | 2 | Active | The LTC1044 is a monolithic CMOS switched capacitor voltage converter which is manufactured using Analog Devices’ enhanced LTCMOS™silicon gate process. The LTC1044 provides several voltage conversion functions: the input voltage can be inverted (VOUT= –VIN), doubled (VOUT= 2VIN), divided (VOUT= VIN/2) or multiplied (VOUT= ± nVIN).Designed to be pin-for-pin and functionally compatible with the popular 7660, the LTC1044 provides significant features and improvements over earlier 7660 designs. These improvements include: full 1.5V to 9V supply operation over the entire operating temperature range, without the need for external protection diodes; two and one-half times lower quiescent current for greater power conversion efficiency; and a "boost" function which is available to raise the internal oscillator frequency to optimize performance in specific applications.Although the LTC1044 provides significant design and performance advantages over the earlier 7660 device, it still maintains its compatibility with existing 7660 designs.ApplicationsConversion of 5V to ±5V SuppliesPrecise Voltage Division, VOUT= VIN/2 ±20ppmVoltage Multiplication, VOUT= ±nVINSupply Splitter, VOUT= ±VS/2 |
| Power Management (PMIC) | 6 | Active | The 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. The supply current drops to 1.5μA at 5V input when the OSC pin is tied to GND or V+.ApplicationsConversion of 10V to ±10V SuppliesConversion of 5V to ±5V SuppliesPrecise Voltage Division: VOUT= VIN/2 ±20ppmVoltage Multiplication: VOUT= ±nVINSupply Splitter: VOUT= ±VS/2Automotive ApplicationsBattery Systems with 9V Wall Adapters/Chargers |
