Power controller IC from ADI for AC/DC and DC/DC converters

Analog Devices has 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 ADP1043A featuring 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.


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.

The other key features:

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.
