Abstract
In accordance with an embodiment, a method of testing a power supply controller includes detecting whether an external switch is coupled between a first supply pin and the second supply pin. If the external switch is detected, the method determines whether there is a short circuit between the second supply pin and the switching output pin. If the short circuit between the second supply pin and the switching output pin is not detected, however, the method determines whether there is a short circuit between a switch control pin and the second supply pin. If the short circuit between the switch control pin and the second supply pin is not detected, the method determines whether there is a conductive path between the first supply pin and the second supply pin when the switch control pin activates the external switch.
