Abstract
A device is configured to control a transition timing of a switching DC/DC converter for providing power to a load device. The load device has a first operational phase that is sensitive to external noise and a second operational phase that is immune to the external noise. The device includes an input terminal coupled to an external device to receive a start signal of the first operational phase for the load device. The device also includes control circuitry configured to, responsive to the start signal, control a transition frequency of the DC/DC converter to avoid transitioning an output of the switching DC/DC converter during the first operational phase.
