Title:
電源制御装置
Document Type and Number:
Japanese Patent JP7386064
Kind Code:
B2
Abstract:
The power supply control device includes a logic circuit for generating a pseudo switch voltage simulating a behavior of a switch voltage generated in the switch output stage, a filter unit that receives input of the pseudo switch voltage and the output voltage or a feedback voltage corresponding to the output voltage and generates a current sense signal simulating a behavior of the inductor current, and a feedback control unit that performs output feedback control of the switch output stage by using the current sense signal.
