Abstract
Method and circuitry for clamping outputs of inactive error amplifiers in battery chargers eliminate delays and prevent oscillatory tendencies. By clamping the output of, for example, an inactive current loop amplifier in response to the output of an active voltage loop amplifier in a battery charging circuit, the inactive amplifier is prevented from saturating, such that it can take over as the controlling loop with minimal delay.
