REACTOR Microelectronics has obtained a patent for high-precision peak current control of switching power supplies, achieving high-precision control of peak current of switching power supplies.
On March 25, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Shaanxi REACTOR Microelectronics Co., Ltd. had obtained a patent entitled "a high-precision peak current control method and circuit for switching power supply", with the authorization announcement number of CN107026569B and the application date of March 2017.
The patent abstract shows that the present invention discloses a high-precision peak current control method for a switching power supply, comprising: S1, detecting the current Ics flowing through the inductor coil of the switching power supply in this cycle, and recording the peak current Icsmax; S2. Compare the current peak Icsmax of this cycle with the preset value Ith, and adjust the value of the inductance threshold current Iset for the next cycle based on the first comparison result; S3. Output the control signal based on the second comparison result between the current Ics of this cycle and the inductance threshold current Iset of this cycle. The present invention also discloses a high-precision peak current circuit, control circuit, and adjustment circuit for a switching power supply. The present invention achieves high-precision control of the peak current of a switching power supply and improves the accuracy of the power supply.
