Based on the special power supply requirements of
the project, the AD8210YRZ (current
monitoring operational amplifier) monitors
the charging current in real time, and its output is fed back to the detection
pin of the TPS5430DDA to adjust the charging voltage of the capacitor. Combined
with the charge-discharge characteristics of the super capacitor, the circuit
realizes high current constant current charging at low voltage and constant
voltage charging when the capacitor terminal voltage increases. This method can
effectively and reasonably improve the charging efficiency of the super
capacitor and meet the design requirements. The product has been put into use
and achieved good results.
