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 QMBTUJD QBDLBHF 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 Low voltage operation voltage reference, can be used as a current limiter. Low external component count Current sink output stage
