Latest Patents

Jong-Woon Hong holds a patent for a "Switching mode power supply for low power operation." This invention describes a switching mode power supply that includes a power supply unit, a mode setting unit, a feedback circuit, and a switching controller. The switching controller is designed to manage a main switch, enabling it to perform a switching operation at a predetermined duty based on the feedback voltage stored in a first capacitor during normal operation. In standby mode, the controller alternates between switching on and off, allowing for variable current input based on the operation mode. This design ensures that the minimum voltage required for the switching controller's operation is maintained, even when the output voltage decreases in standby mode, thereby minimizing unnecessary power consumption.
