Publication number: 20250047189Abstract: A control device includes a first capacitor, a drive controller, a constant current source, a discharge-controlled current source, a current mirror, and a sample-and-hold circuit. The constant current source generates a constant current. The discharge-controlled current source is coupled to the constant current source and the first capacitor. The current mirror is coupled to the first capacitor and the primary side of a primary-side switch. The current mirror generates a copy current, thereby generating a copy voltage across the first capacitor. When the drive controller turns on the primary-side switch, the sample-and-hold circuit drives the discharge-controlled current source to sample and hold a control current from the constant current and the copy current. When the node voltage is higher than the copy voltage, the comparison circuit drives the drive controller to turn off the primary-side switch.Type: ApplicationFiled: October 24, 2023Publication date: February 6, 2025Inventors: KE-HORNG CHEN, YING-FENG WU, YU-CHOU KO, KUO-LIN ZHENG, KE-MING SU
