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.
| Input Voltage | 350 V to 400 V dc |
|---|---|
| Output Voltage | 12 V |
| Output Current | 25 A |
| Efficiency | 91.5% |
| Switching Frequency | 148.8 kHz |
| Ambient Temperature | 0 to 50 ºC |
The board features an interleaved two-switch forward topology with synchronous rectification.
The board uses an I2C serial interface to connect to a PC running Windows 2000, Windows NT, or Windows XP.
