VOLTAGE OUTPUT CIRCUIT AND ELECTRONIC CIGARETTE

A voltage output circuit (100) and an electronic cigarette. The voltage output circuit (100) comprises: a control chip (U6) comprising a first control signal input end (20), a second control signal input end (21), and a modulated signal output end (23), where the first control signal input end (20) is electrically connected to a first control signal output end (24) by means of a suction detection element (J3), the second control signal input end (21) is connected to a second control signal output end (37) of a touch sensing chip (U8), and a touch input pin (25) of the touch sensing chip (U8) is connected to a touch panel; and a step-down switch chip (U2) comprising a first channel end (26), a first control end (27), and a second channel end (28), where the first channel end (26) of the step-down switch chip (U2) receives a system supply voltage (VCC_BAT), the first control end (27) of the step-down switch chip (U2) is connected to the modulated signal output end (23) of the control chip (U6), and when the first control signal input end (20) and/or the second control signal input end (21) receives active level, the control chip (U6) controls the second channel end (28) to output a driving voltage. The voltage output circuit (100) solves the problem in the electronic cigarette of single light-up mode.
