Abstract
A converter control circuit includes a terminal to be coupled to a switch node. The control circuit includes a valley sensing circuit coupled to the terminal and detects valleys in an oscillating voltage on the switch node. The valley sensing circuit has a first output and asserts a first control signal on the first output indicative of occurrence of a valley. A logic gate has a second output and asserts a second control signal on the second output to turn on a switching transistor. A switch-on control circuit has a first input and a second input. The first input couples to the first output. The second input couples to the second output. The switch-on control circuit asserts a third control signal to turn on the switching transistor responsive to the second control signal indicating that the switching transistor is to be on while the first control indicates a valley.
