Beschreibung
Zusammenfassung:	The invention relates to the technical field of DAC output stage control, and particularly discloses a boost converter and method suitable for power supply of a DAC output stage, the DAC output stage comprises an output PMOS tube and a load resistor, the source electrode of the output PMOS tube is electrically connected with the output voltage of the boost converter, the drain electrode of the output PMOS tube is electrically connected with one end of the load resistor, the other end of the load resistor is electrically connected with the ground, and the other end of the load resistor is electrically connected with the ground. The converter comprises a high-side voltage sampling circuit, the input of which is electrically connected with the drain electrode of an output PMOS tube, and which is used for converting the source-drain voltage of the output PMOS tube into a voltage signal based on the ground; and the input of the boost circuit is electrically connected with the output end of the high-side voltage sa
