MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202517098995 A) filed by Vanchip (TIANJIN) Technology Co. Ltd., Tianjin, China, on Oct. 14, for 'peak current control circuit and method for adaptive ramp compensation, and dc-dc converter.'
Inventor(s) include Li, Chunling; and Wang, Yongshou.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "Disclosed in the present invention are a peak current control circuit and method for adaptive ramp compensation, and a DC-DC converter. The peak current control circuit comprises an inductive-current detection module, a control signal generation module, an adaptive-ramp-compensation current generation module, a DC voltage adjustment module, a first current generation module and a second current generation module, wherein a first input end and a second input end of the inductive-current detection module are respectively connected to two ends of an inductor in the DC-DC converter; an input end of the first current generation module is connected to an output voltage end of the DC-DC converter; an input end of the second current generation module is connected to an input voltage end of the DC-DC converter; and an output end of the control signal generation module is connected to an inverting input end of a PWM comparator in the DC-DC converter, so as to form a control current loop. The peak current control circuit can adaptively adjust the magnitude of a ramp compensation current."
The patent application was internationally filed on Mar. 30, 2024, under International application No.PCT/CN2024/085106.
