摘要： The present disclosure discloses a switching mode power supply with constant peak current mode control. During the operation of the switching mode power supply, in one hand, the current flowing through a high-side switch is sensed and compared to a current reference signal to control the turning off of the high-side switch; in the other hand, the output voltage is sensed and compared to a voltage reference signal to control the turning on of the high-side switch. In addition, the current reference signal may be adjusted to a lower value when the switching mode power supply enters light load condition. By using the above control method, the system performance is highly increased.

摘要： The present disclosure provides a method and system for processing table of content (TOC) access overflow in an application. The method may determine whether there occurs a TOC access overflow within an object file during linking the object file that may be generated from the compiling. If the TOC access overflow occurs within the object file, then the source file corresponding to the object file may be re-compiled so as to generate an object file having no TOC access overflow, and the object file may be re-linked to generate an executable file of the application. The present disclosure may adopt two-pass compiling and a dual-instruction TOC access in a form of two pieces of instructions that may be generated for TOC entries within which TOC overflows generally occur.
