Abstract
A new architecture for buck LED drivers and buck DC-DC converters is disclosed for providing response to both line and loads. The architecture uses a new average current mode control scheme that does not use an error amplifier to regulate the current in the inductor in the buck converter. Even though there is no oscillator the switching frequency remains constant over line and load. The architecture provides a low cost solution with very fast response times.
