ADI digital power controller ADP1046 targets high efficiency isolated power supply-EEWORLD

Collect

China, Beijing – Analog Devices, Inc. (NASDAQ: ADI), a global leading supplier of high-performance signal processing solutions, recently launched the ADP1046 digital power controller for high-efficiency AC-DC and isolated DC-DC power systems. The ADP1046 is a flexible controller with 7 PWM (pulse width modulation) logic outputs that can be easily programmed through an I2C interface and an easy-to-use graphical user interface (GUI). The device can be used to control and drive most power topologies, including resonant mode for high efficiency.

The ADP1046 is pin-compatible with ADI's acclaimed ADP1043A, but offers advanced features and increased 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-band control to enhance efficiency over the entire load range. The ADP1046 is designed for high efficiency AC-DC power supplies (for server, storage, and networking applications) and isolated DC-DC power supplies (including intermediate bus and radio power amplifier applications).

More information about the ADP1046 Digital Power Controller

The ADP1046 power controller can be easily programmed through an intuitive graphical user interface (GUI), so customers can design and optimize robust systems without the need for complex code programming as required for DSP (digital signal processor)-based alternatives. The I2C interface allows key parameter data to be read back, providing rich programmability for operation and fault handling. Based on ADI's precision, high-speed ADC technology, the ADP1046 is suitable for parallel and redundant power supply operation, providing analog and digital current sharing functions, and controlling external OR-FETs for redundant power supply applications.

ADP1046 key features and benefits:

Flexible, easy-to-use digital controller for high-efficiency AC-DC and isolated DC-DC power systems

GUI programming capabilities help simplify use and shorten time to market

Digital control loop with 7 logic PWM signals to drive most power topologies including resonant mode for high efficiency

Voltage feed-forward for improved line transient response

Dedicated loop filters for soft-start, light load, and normal load to improve loop response and enhance design flexibility

Adaptive dead-band control for enhanced efficiency across the entire load range

Current sharing and OR control for parallel and redundant systems

8K bytes of user accessible EEPROM

I2C interface allows extensive programming and telemetry

Supply, quotation and supporting products

The ADP1046 digital controller is a companion device to the company’s high-speed MOSFET drivers, Analog Devices’ iCoupler® digital isolators for isolated power systems, and the ADP1047 and ADP1048 power factor correction digital controllers for AC-DC systems. These devices make it easy to implement intelligent power management to improve energy efficiency.
