Description
The LTC®1983-3 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 100m A of output current. The devices can operate in open loop mode (creating a
- VIN supply) or regulated output mode depending on the input supply voltage and the output current. The LTC1983-3/LTC1983-5 have many useful...
