Embodiment Construction
[0032] Below in conjunction with accompanying drawing and specific embodiment, describe technical solution of the present invention in detail:
[0033] The trimming switch circuit provided by the present invention includes a trimming code loading module and a switch control module. The switch control module is connected to an externally given first input signal en and a second input signal enP, and controls the switch control according to the second input signal enP. The module works or shuts down, and generates the first control signal PD, the second control signal PD_N and the timing signal CK according to the first input signal en and the feedback output signal vin to control the modification code loading module; the modification code loading The module works or shuts off according to the first control signal PD and the second control signal PD_N. When the fuse fuse is blown by the control signal v_trim of the fuse fuse, the pulse level of the corresponding output signal VOU...
