Abstract:
A switch-mode power supply includes a converter, a controller and a charging current. The charging current includes a logic circuit, a first current source and a second current source, to generate a charging current proportional to an input voltage of the switch-mode power supply, and also to generate a logic control signal indicative of either of two operation modes.
