Abstract
A burn-in system includes single and dual power modes, a testing stage, first and second power stages, a single mode power control circuit and a dual mode power control circuit. When the burn-in system is in the single power mode, the first power stage produces a first power output to the testing stage based on a single mode error signal generated by the single mode power control circuit. When the burn-in system is in the dual power mode the first power stage produces the first power output and the second power stage produces a second power output in response to a dual mode error signal produced by the dual mode power control circuit. The first and second power outputs are coupled together when the burn-in system is in the dual power mode. In one embodiment, the first and second power stages each include a pulse width modulator controller that receives one of the error signals produced by the single mode and dual mode power control circuits depending on the power mode of the burn-in system, and controls the first and second power outputs accordingly.
