Apparatus for supplying power to integrated circuit e.g. processor, has controller that controls switch arranged in electric conducting line, depending on ratio between different supply voltages

摘要

#CMT# #/CMT# The power supply apparatus has an electric conducting line (110) with a terminal (210) for receiving a supply voltage and a terminal (211) for supplying the supply voltage. A conducting line (112) has terminals (212,213) for receiving and supplying the supply voltage respectively. A switch (230) is arranged in the conducting line (110). A controller (232) controls the switch depending on a ratio between the different supply voltages. A connector (234) connects the terminals (211,213). #CMT# : #/CMT# An independent claim is included for a method for turning OFF the power supply. #CMT#USE : #/CMT# Apparatus for supplying power to integrated circuit such as processor. Can also used in supplying power to other integrated circuits such as application specific integrated circuit (ASIC) and field-programmable gate array (FPGA). #CMT#ADVANTAGE : #/CMT# Improved turning OFF of the power supply is achieved so that damage of processor is prevented. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the block diagram and circuit diagram of the power supply apparatus, and flow diagram explaining the operation process of power supply apparatus. 110,112 : Electric conducting lines 210-213 : Terminals 230 : Switch 232 : Controller 234 : Connector.
