Abstract:
1. A hysteretic control conversion circuit, comprising: a P-channel metal oxide semiconductor (PMOS) transistor; an N-channel metal oxide semiconductor (NMOS) transistor; a first voltage divider resistor; a comparator; a logic controller; and a negative feedback module, wherein the PMOS transistor and the NMOS transistor are connected in series between a voltage input terminal and a ground terminal, wherein the first voltage divider resistor is connected in series between a voltage output terminal and the ground terminal, wherein an output terminal of the comparator is connected to an input terminal of the logic controller, wherein two output terminals of the logic controller are respectively connected to grid electrodes of the PMOS transistor and the NMOS transistor, and wherein the negative feedback module is connected between the voltage output terminal and the input terminal of the comparator and is configured to perform negative feedback control over an output voltage of the hysteretic control conversion circuit and clamp the output voltage to a preset reference voltage.
