Overview
Data Sheet FEATURES Digital Power Factor Correction Controller with Accurate AC Power Metering ADP1047/ADP1048 GENERAL DESCRIPTION The ADP1047/ADP1048 are digital power factor correction (PFC) controllers that provide accurate input power metering capability and inrush current control for ac/dc systems.
The ADP1047 is designed for single phase PFC applications; the ADP1048 is designed especially for 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.
The ADP1047/ADP1048 allow users to optimize system performance, maximize efficiency across the load range, and reduce design time to market.
The ADP1047/ADP1048 provide accurate rms measurement of input voltage, current, and power.
This information can be reported to the microcontroller of the power supply via the PMBus interface.
