Abstract
The invention discloses a hysteretic control conversion circuit. The circuit includes a PMOS transistor and an NMOS transistor that are connected in series between a voltage input terminal and a ground terminal, a first voltage divider resistor string connected in series between a voltage output terminal and the ground terminal, a comparator, and a logic controller, where an output terminal of the comparator is connected to an input terminal of the logic controller, and two output terminals of the logic controller are respectively connected to grid electrodes of the PMOS transistor and the NMOS transistor. The hysteretic control conversion circuit also includes: a negative feedback module connected between the voltage output terminal and the input terminal of the comparator, and 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.
