DESCRIPTION

The TSM1011 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes.

The TSM1011 integrates one voltage reference and two operational amplifiers (with ORed outputs —common collectors).

The voltage reference combined with one operational amplifier makes it an ideal voltage controller. The other operational amplifier, combined with few external resistors and the voltage reference, can be used as a current limiter.

■ Constant voltage and constant current control
