The onboard 6-bit digital-to-analog converter (DAC) provides a voltage output of 0.83V to 1.6 V, with a tolerance of ±0.5% over the full temperature range and input range. The NCP531x features differential current sense inputs for each phase to help insure signal integrity and noise immunity in the challenged PC layouts. It also features inductor current sensing that provides an accurate, loss-less current sense scheme. In addition to providing two extra phases, the NCP5316 features per phase current limit and pins that provide a signal scaled to both the total inductor current and the per phase current.
