ADP1046ACPZ-R7

Overview

The ADP1046ACPZ-R7 is a flexible digital secondary side controller designed for AC-to-DC and isolated DC-to-DC applications. It integrates typical PWM controller functions, including seven PWM control signals and a digital control loop with programmable filters. The device supports voltage feedforward, remote/local sense, and synchronous rectifier control. It features an I2C interface for programming and telemetry, extensive fault detection, and user-accessible EEPROM.

Feature Summary

• Integrates all typical PWM controller functions with a digital control loop
• Supports primary and secondary side current sensing with synchronous rectifier control
• Includes an I2C interface for extensive programming and telemetry capabilities

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 the specific suffix R7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the component matches the LFCSP package requirements for your design.

Selection Notes

Select this controller for applications requiring digital flexibility and high efficiency in isolated topologies. It serves as a pin-compatible enhancement to the ADP1043A, offering improved loop response and voltage feedforward. Consider its I2C capability for advanced system monitoring and configuration needs.

Part Context

This component belongs to the ADP1046A series of digital controllers. It is designed to replace or enhance traditional analog PWM controllers by providing programmable parameters via software. The part is manufactured by Analog Devices Inc. and targets high-performance power management solutions.

Replacement Considerations

The ADP1046A is pin-compatible with the ADP1043A. Verify that the enhanced features such as voltage feedforward are compatible with the existing circuit design before substitution.
