产品概述
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.
