General Description

TS1051 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current)

mode. TS1051 integrated one voltage reference, two operational amplifiers, and a current sensing circuit. The voltage

reference combined with one operational amplifier make it an ideal voltage controller, and the other low voltage

reference combined with the other operational amplifier make it an ideal current limiter for output low side current

sensing.

The current threshold is fixed, and precise. The only external components are:

* A resistor bridge to be connected to the output of the power supply (Adapter, battery charger) to set the voltage

regulation by dividing the desired output voltage to match the internal voltage reference value.

* A sense resistor having a value and allowable dissipation power which need to be chosen according to the internal

voltage threshold.
