LTC1044 - Switched Capacitor Voltage Converter
LTC1044 - Switched Capacitor Voltage Converter - Linear Technology（凌力尔特）
功能描述
The H (Metal Can), J (Ceramic), and K (Metal Can) Packages From Linear Technology Are Now Obsolete
The LTC1044 provides several voltage conversion functions: the input voltage can be inverted (VOUT=-VIN), doubled (VOUT=2 VIN), 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; 21/2 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.
