GENERAL DESCRIPTION

The

(PFC) controllers that provide accurate input power metering

capability and inrush current control for ac/dc systems. The

ADP1047

ADP1048

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

performance, maximize efficiency across the load range, and

reduce design time to market.

The

of input voltage, current, and power. This information can be

reported to the microcontroller of the power supply via the

PMBus interface.
