Package典型应用典型应用描述The LTC1983-3 and LTC1983-5 are inverting charge pump DC/DC converters that produce negative regulated outputs. The parts require only three tiny external capacitors and can provide up to 100mA of output current. The devices can operate in open loop mode (creating a -V IN supply) or regulated output mode depending on the input supply voltage and the output current.The LTC1983-3/LTC1983-5 have many useful features for portable applications including very low quiescent current (25μA typical) and a zero current shutdown mode programmed through the SHDN pin.The LTC1983-3/LTC1983-5 are over-temperature and short-circuit protected. The parts are available in a 6-pin low profile (1mm) ThinSOT package.
