Summary
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.
Features:
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
