Filed: 2000-01-21
Abstract: PURPOSE: A synchronous rectifier flyback circuit is provided to minimize loss occurring at conduction of a parasitic diode of a MOSFET as a secondary switch of a synchronous rectifier at continuous and discontinuous modes, and to perform zero voltage switching at the discontinuous mode. CONSTITUTION: A synchronous rectifier flyback circuit comprises a pulse width modulation controller(70) which generates a pulse width modulation signal. A switch(SW) is switched according to the pulse width modulation signal from the pulse width modulation controller(70). A transformer(T) induces a primary voltage into a secondary according to a switching operation of the switch(SW). A synchronous rectifier(50) rectifies a secondary voltage of the transformer(T). An SR gate driver(80) delays a gate driving signal from the pulse width modulation controller(70), and compares the delayed signal with a reference voltage from the pulse width modulation controller(70). The SR gate driver(80) amplifies the comparison value to provide the amplified result as the driving signal of the synchronous rectifier(50).

Filed: 2000-02-29
Abstract: PURPOSE: A method for controlling the power of a memory is provided to shorten a booting time by making a system entered into a power saving mode as a main control part jumps to a specific address stored in a memory if the system is initialized. CONSTITUTION: In a state that the power of a system is off, a power supply part supplies backup power to a memory part so that various resource data necessary for system operation can be stabilized(S101). A central control part judges whether the input of a system initialization signal to transfer the power-off state into a power-on state is detected(S102). In case that the input of the power-on signal for system initialization is detected, the central control part jumps to the 0X000 address of the memory part(S103). The central control part searches the table fixed to the 0X000 address for an address for the next jumping(S104) and jumps to the searched address so that the system can be entered into a power saving mode(S105). Then the central control part completes initialization booting by initializing the hard disk, the floppy disk drive, and other peripherals(S106).
