TSM1013 Constant Voltage and Constant Current Controller for Battery Chargers and Adaptors Constant voltage and constant current control Low voltage operation Low external component count Current sink output stage Easy compensation VOLTAGE REFERENCE D SO-8 Fixed output voltage reference 2.5V 0.5% and 1% Voltage precision DESCRIPTION TSM1013 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and S CC (constant current) mode. Mini SO8 TSM1013 integrates one voltage reference and two operational amplifiers. The voltage reference combined with one PIN CONNECTIONS (top view) operational amplifier makes it an ideal voltage controller. The other operational, combined with few external resistors and the voltage reference, can be used as a current limiter.
