Abstract
An open-loop resonate converter includes: a transformer having a first winding on a primary side of the open-loop resonate converter and a second winding on a secondary side of the open-loop resonate converter; a resonant tank coupled to the first winding of the transformer and configured, at a first fixed frequency, to provide a constant LED current over a voltage range at the secondary side without feedback from the secondary side; and a circuit configured to modulate switching of the resonant tank between the first fixed frequency and a second fixed frequency higher than the first fixed frequency based on a dimming control signal input to the circuit, such that the resonant tank is switched at the first fixed frequency for longer durations when the dimming control signal indicates less dimming and for shorter durations when the dimming control signal indicates more dimming.
