LTC1044S8 - Switched Capacitor Voltage Converter - Linear Technology（凌力尔特）

功能描述

The LTC1044 is a monolithic CMOS switched capacitor voltage converter which is manufactured using Linear Technology's enhanced LTCMOSTM silicon gate process. The LTC1044 provides several voltage conversion functions: the input voltage can be inverted (VOUT=-VIN), doubled (VOUT=2 VIN), divided (VOUT=VIN/2) ormultiplied (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 protectiondiodes; 21/2 times lower quiescent current for greater power conversionefficiency; and a "boost" function which is available to raise the internaloscillator 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 still maintains its compatibility with existing 7660 designs.
