GATE DRIVER SWTCIH CONTROL CIRCUIT AND POWER SUPPLY DEVICE COMPRSING THE GATE DRIVER CIRCUIT

摘要

The present invention relates to a switch control circuit and a power supply device including a gate drive circuit and a gate drive circuit. The gate driving circuit generates a gate voltage of the power switch. The gate driving circuit generates a first control signal for varying a rising slope of the gate voltage at a first time point when a first delay period elapses from a time point of the gate voltage rise, and a second delay time period from the first time point. And a delay control circuit for generating a second control signal for varying the rising slope of the gauge voltage at this time point, and a temperature compensation circuit for varying the first delay period according to temperature.
