Embodiment 1
[0042] Please refer to figure 1 , which is a method flowchart of the first embodiment of a method for reducing power consumption provided in the specific embodiments of the present invention. As shown, the method includes:
[0043] Step 101: the voltage sampling module collects the voltage of the output capacitor.
[0044] Step 102: When the collected voltage is a preset low voltage, the optocoupler feedback module receives the preset low voltage and outputs a high level; the deep standby control module receives the high level and controls power management The module starts to work; the power management module receives the high level, outputs a corresponding constant voltage according to the high level, and charges the output capacitor.
[0045] When the voltage of the capacitor is not enough to provide a constant voltage for the load alone, the voltage sampling circuit collects the preset low voltage, the optocoupler feedback module receives the preset low voltage, processe...
Embodiment 2
[0053] Please refer to figure 2 , which is a method flowchart of the second embodiment of a method for reducing power consumption provided in the specific embodiments of the present invention. As shown, the method includes:
[0054] Step 201: the voltage sampling module collects the voltage of the output capacitor.
[0055] Step 202: When the collected voltage is a preset low voltage, the optocoupler feedback module receives the preset low voltage and outputs a high level; the deep standby control module receives the high level and controls power management The module starts to work; the power management module receives the high level, outputs a corresponding constant voltage according to the high level, and charges the output capacitor.
[0056] The deep standby control module receives the relatively high level, and controls the power management module to start working, including: the trigger switch of the deep standby control module receives the relatively high level, and...
