ADP1046AACPZ-R7

Overview

The ADP1046AACPZ-R7 is a flexible digital secondary side controller designed for AC-to-DC and isolated DC-to-DC power supply applications. It integrates typical PWM controller functions, including seven PWM control signals and a digital control loop with programmable loop filters. The device features voltage feedforward, remote/local voltage sense, primary/secondary current sense, synchronous rectifier control, and I2C interface capabilities.

Feature Summary

• Integrates comprehensive PWM control functions with a digital control loop and programmable filters
• Supports voltage feedforward and dedicated soft start filter for enhanced efficiency
• Provides extensive fault detection, protection, and telemetry via I2C interface

Applications

• AC-to-DC power supplies
• Isolated DC-to-DC power supplies
• Redundant power supply systems
• Server, storage, network, and communications infrastructure

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel packaging configuration. Ensure compliance with RoHS directives and check for moisture sensitivity handling requirements during storage and assembly processes to maintain device integrity.

Selection Notes

Select this controller for designs requiring precise digital regulation of isolated power stages. It serves as an enhancement over the ADP1043A with improved loop response and voltage feedforward. Evaluate compatibility with synchronous rectification schemes and current sharing requirements for multi-phase or redundant configurations in high-efficiency systems.

Part Context

This component belongs to the ADP1046A series of digital controllers from Analog Devices. It is pin-compatible with the ADP1043A but offers advanced features like voltage feedforward. The part is categorized under PMIC - Power Management ICs and Switching Controllers, targeting high-performance isolated power conversion needs.

Replacement Considerations

The ADP1043A is a pin-compatible predecessor within the same family. Verify if the enhanced loop response and voltage feedforward features of the ADP1046A are necessary for the specific application design before substituting.
