ADP1047ARQZ-R7

Digital Power Factor Correction Controller with Accurate AC Power Metering

Analog Devices 

Data Sheet

The combination of a flexible, digitally controlled PFC engine

and accurate input power metering facilitates the adoption

of intelligent power management systems that are capable of

making decisions to improve end-user system efficiency. The

device supports additional efficiency improvements through

programmable frequency reduction at light load and the

capability to reduce the output voltage at light load.

The ADP1047/ADP1048 provide enhanced integrated features

and functions; the inrush current and soft start control functions

provide significant component count reduction with easy design

optimization.

ADP1047/ADP1048

The devices are designed for high reliability, redundant power

supply applications and have extensive and robust protection

circuitry: independent overvoltage protection (OVP) and

overcurrent protection (OCP), ground continuity monitoring,

and ac sensing. Internal overtemperature protection (OTP)

is provided whereby the external temperature can be recorded

via an external sensing device.

The internal 8 kB EEPROM stores all programmed values

and allows standalone control without a microcontroller. All

parametric reporting and adjustments can be programmed via

an easy-to-use GUI. No complex programming is required.

The ADP1047/ADP1048 operate from a single 3.3 V supply. The

devices are available in a 24-lead QSOP package that is specified

over an ambient temperature range of −40°C to +85°C.
