Abstract

DAC control logic for controlling a DAC for supplying a target voltage VTARGET to a switching converter is disclosed. The DAC logic comprises control logic which is configured, in response to DAC ramp-down, to decrement DAC input code supplied to the DAC in a series of steps. The DAC control logic is configured, for at least some of the steps during ramp down, to wait until at least one switching cycle has occurred in the switching converter before decrementing the DAC input code from a current value to a new value.
