ADP1048 Datasheet PDF | Analog Devices

Analog Devices ADP1048

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. The ADP1047/ADP1048 allow users to optimize system performance, maximize efficiency across the load range, and reduce design time to market.

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; 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 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. Flexible digital power factor correction (PFC) controller Single phase operation (ADP1047); interleaved and bridgeless operation (ADP1048) True rms ac power metering Enhanced dynamic response Optimized light load efficiency performance Output voltage adjustment Frequency reduction Inrush current co...
