Analog Devices, Inc. (ADI), a
global leader in high-performance semiconductors for
signal-processing applications, today introduced the ADP1046
digital power controller for high efficiency AC-to-DC and isolated
DC-to-DC power supply systems. The ADP1046 is a flexible controller
with seven PWM (pulse width modulation) logic outputs that can be
easily programmed using an easy-to-use graphic user interface (GUI)
with I2C interface. The device can be used to control and drive
most power supply topologies including resonant mode for high
efficiency. The ADP1046 is pin compatible with ADI’s award winning,
ADP1043A but offers advanced features and greater flexibility,
including voltage feed-forward for fast line transient response;
dedicated control loop configuration to improve loop response and
reduce output noise; and adaptive dead-time control for enhanced
efficiency across the entire load range. The ADP1046 is
specifically designed for high efficiency AC-to-DC power supplies
used in server, storage and networking applications and isolated
DC-to-DC supplies including intermediate bus and radio power
amplifier applications.

More About the ADP1046 Digital Power Controller
The ADP1046 power controller is easily programmed using an
intuitive graphical-user interface which enables customers to
design and optimize robust systems without the complex code
programming required by alternative DSP (digital signal processor)
based devices. The I2C interface allows read-back of key parametric
data and enables extensive programmability of operation and fault
handling. Based on Analog Devices’ precision, high speed A/D
converter technology, the ADP1046 is suited to parallel and
redundant power supply operation and offers analog and digital
current sharing functions and control of the external OR-FET for
redundant power supply applications.
Key ADP1046 Features and Benefits:
- Flexible, easy to use, digital
controller for high efficiency AC-to-DC and isolated DC-to-DC
power supply systems.
- GUI programmability promotes ease of
use and reduces time to market.
- Digital control loop with seven logic
PWM logic signals to drive most power supply topologies including
resonant mode for high efficiency.
- Voltage feed-forward improves line
transient response.
- Dedicated loop filters for soft start,
light load and normal load offer improved. loop response and
enhance design flexibility.
- Adaptive dead-time control for improved
efficiency across the entire load range.
- Current share and OR-ing control for
use in parallel and redundant systems.
- User accessible 8K byte EEPROM.
- I2C interface allows extensive
programming and telemetry.

The ADP1046 digital controller is designed to complement the
high-speed MOSFET drivers and ADI’s iCoupler® digital isolators in
isolated power systems, and the ADP1047 and ADP1048 power factor
correction digital controllers in AC-to-DC systems. These devices
facilitate easy implementation of intelligent power management for
greater energy efficiency.
