Arent Fox LLP.
DC-DC converter with step-up and step-down control capable of varying the offset voltage of the PWM triangle
When both step-up PWM control and step-down PWM controls are executed, the offset of the ON/OFF switching timing for step-up PWM control and/or the offset of ON/OFF switching timing for step-down PWM control are changed to become identical. By synchronizing ON/OFF switching timing for step-up PWM control and ON/OFF switching timing for step-down PWM control, the loss on switching can be reduced.
