Digital power controller targets high efficiency, isolated power supplies

Analog Devices Inc. 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 ADI’s, 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.

Key highlights:

• 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.
