TSM1012 Low consumption voltage and current controller for battery chargers and adapters Datasheet - production data Description The TSM1012 is a highly integrated solution for SMPS applications requiring the CV (constant voltage) and CC (constant current) mode. % 40 TheTSM1012 device integrates one voltage Q B reference and two operational amplifiers (with ORed outputs - common collectors). Features The voltage reference combined with one operational amplifier makes it an ideal voltage Constant voltage and constant current control controller. The other operational amplifier, Low consumption combined with few external resistors and the voltage reference, can be used as a current Low voltage operation limiter.
