を特徴とする二次電池充電回路。[Claims for Utility Model Registration] It has a switching element and a smoothing circuit, and by controlling the switching operation of the switching element according to fluctuations in the output voltage, the input DC low voltage is boosted and a constant voltage is output. a step-up switching power supply circuit that detects a charging current flowing from the step-up switching power supply circuit to the secondary battery and controls the charging current supplied to the secondary battery, the step-up switching power supply circuit comprising: When the current control circuit detects a current exceeding the set current when the output voltage increases until a constant voltage is output from the circuit,
The detection signal is applied to the step-up switching power supply circuit, and the switching element is controlled assuming that the output voltage of the step-up switching power supply circuit has fluctuated, thereby causing the current control circuit to output a constant current to charge the secondary battery. A secondary battery charging circuit characterized in that:
