ADP1048

Digital Power Factor Correction Controller with accurate AC Power Metering
Manufactured by:

Product Details

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.

Applications

  • AC/DC power supplies for applications
    Computing Server & Storage

EVAL-ADP1048 Circuit Diagram

Product Details

The evaluation board features an interleaved boost PFC topology operating at 100KHz switching frequency. Its output is rated at deliver 385V, 600W with a universal AC input ranging from 85-265V. The board features the ADP1048 digital controller for offering power factor correction and accurate AC power metering. It also provides protection features like AC line fault protection, OCP and OVP.

Product Details

The USB to I2C interface is used for communicating between a digital power management device (like the ADP1043A) and the configuration software that runs on a computer. It also supplies 5V and 0.5A to power up the daughter card / evaluation boards.


This same USB to I2C interface connector is used for the ADP1043A, ADP1047, ADP1048, and other digital power management devices.
