Zusammenfassung:	The utility model relates to a solar charging control circuit with MPPT function. Is the circuit by photovoltaic cell board, DC- the DC module, the battery, the LDO stabiliser, operational amplifier,the diode, electric capacity, resistance R1~R4 constitutes. Photovoltaic cell board and DC- does the DC module link to each other, DC- the DC module links to each other with the battery. The LDO stabiliser links to each other with the photovoltaic cell board, the output links to each other with resistance R3. Operational amplifier pin 3 links to each other with another pin of resistance R3, pin 2links to each other with resistance R1, R2, pin 8 links to each other with the LDO stabiliser, pin 1 and DC- the DC module links to each other. The positive pole of diode links to each other with operational amplifier's pin 3, the negative pole links to each other with resistance R4's. Electric capacity links to each other with the LDO stabiliser. Compared with the prior art, the utility model discloses beneficial effect i
