Introduction

Seunguk Yang is a prominent inventor based in Anyang, South Korea. He has made significant contributions to the field of power supply devices and light-emitting diode (LED) control circuits. With a total of 18 patents to his name, Yang's work showcases his expertise and innovative spirit.

Latest Patents

One of Yang's latest patents is the "Coupling structure of gate driver in power supply device." This invention involves a power supply device that includes a power switch, which is controlled by a gate voltage. A sense resistor is utilized to develop a sense voltage from the switch current flowing through the power switch. The peak of the primary-side current is detected from this sense voltage. The gate driver features a pair of switches that generate the gate voltage based on a control signal. When the low-side switch is activated, the gate voltage of the power switch decreases as a sink current flows through a transistor.

Another notable patent is the "Light emitting diode control circuit with wide range input voltage." This LED control circuit comprises an inductor current sense circuit, which includes a high-side diode string, a low-side diode string, and a sense resistor. The circuit receives an input voltage connected to the high-side diode string. The low-side diode string connects to a switch through an inductor. The sense voltage developed on the sense resistor is sensed by a controller integrated circuit (IC), which can handle a breakdown voltage specification lower than the input voltage.
