The ADP1048ARQZ-R7 is a Digital Power Factor Correction Controller with accurate AC power metering. It provides accurate input power metering capability and inrush current control for ac/dc systems. The device is designed for single phase PFC applications, especially interleaved and bridgeless PFC applications. The digital PFC function is based on a conventional boost PFC with multiplication of the output voltage feedback combined with the input current and voltage to provide optimum harmonic correction and power factor for ac/dc systems. All signals are converted into the digital domain to provide maximum flexibility; all key parameters can be reported and adjusted via the PMBus? interface. It allows users to optimize system performance, maximize efficiency across the load range and reduce design time to market. The ADP1048W provides accurate rms measurement of input voltage, current and power.
