Analog Devices ADP1046 Evaluation Board User Guide UG-320
This document is the User Guide (UG-320) for the Analog Devices ADP1046 evaluation board. It describes the board's implementation of an interleaved two-switch forward topology featuring the ADP1046 controller, designed for a 12 V/25 A regulated output from a 400 V DC input. The guide explains the reference design contents, circuit description, and advantages of the interleaving approach.

What are the main causes of noise injection in an electromagnetic circuit?
The four main causes are common impedance coupling, capacitive coupling, inductive coupling, and radiation.
What is the recommended resistor tolerance for the RES pin?
A 0.1% resistor is recommended because the tolerance of the internal clock frequency is directly proportional to the accuracy of the RES pin resistor.
What is the ADP1046 designed for?
It is a digital secondary side controller designed for ac-to-dc and isolated dc-to-dc applications.
