Abstract:
A bi-level current configurable driver is provided. The driver includes a feedback circuit, a driver circuit providing a driver signal to a half bridge inverter, and a step-dim interface coupled to a first alternating current input line, a second alternating current input line, and a neutral line, providing voltage to the driver circuit. The driver also includes a first feedforward circuit coupled to the step-dim interface, where the first feedforward circuit receives a first signal from the step-dim interface based on the states of the first alternating current input line, the second alternating current input line, and the neutral line. In a first state, the driver provides full current to a load, and in a second state, the driver provides less than full current to the load.
