General Description
TS1052 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant
current) mode. TS1052 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
* A sense resistor having a value and allowable dissipation power which need to be chosen according to the
