ADP1048-600-EVALZ: PFC 600W, 85 ~ 265VAC


This evaluation board features the ADP1048 in a typical AC/DC switching power supply in an interleaved boost power factor correction (PFC) topology. The circuit is designed to provide a rated load of 385V/600W from an AC input voltage source of 85 to 265 VRMS AC.

The ADP1048 provides functions all the functions necessary for active PFC circuit plus accurate AC power metering. It achieves near-unity power factor, low distortion of the input current, the output voltage regulation, over current protection, AC line fault detection and protection, over temperature protection, and power supply shutdown. It also can optimize light load efficiency performance using output voltage adjustment and frequency reduction.


  • Interleaved Boost PFC topology providing high power factor and low THD

  • Protection features for AC line input and high voltage output

  • Current balancing between two phases

  • High efficiency

  • I2C serial interface to PC

  • Software GUI

  • Programmable digital filters

  • Programmable response to faults Programmable inrush control Accurate AC power metering Digital Calibration and trimming
