A drive control circuit, a driving method, a circuit board, and an air conditioner. The motor drive control circuit comprises a first power module (PM1) and a second power module (PM2) that are connected on two sides of an open winding motor, a first switch group (KY1), a controller, a totem pole PFC circuit (200), and a buck switch circuit (300); the controller is connected to the totem pole PFC circuit (200) so as to control the totem pole PFC circuit (200) to reach at least one of the following states: a diode rectification state, a low-frequency switch state, and a high-frequency switch state; and a diode rectification mode and a low-frequency switch mode that match the totem pole PFC circuit (200). The controller controls the buck switch circuit (300) to carry out buck output and supply to the first power module a voltage that is suitable for low-frequency work.
