The ADP1051-240-EVALZ evaluation board and the ADP1051DC1-EVALZ daughter card feature the ADP1051 in a dc-to-dc switching power supply in full bridge topology with synchronous rectification. The circuit is designed to provide a rated load of 12 V, 20 A from a dc input voltage source of 36 V dc to 75 V dc. The ADP1051 provides functions such as output voltage regulation, synchronization, constant current control, prebias start up, direct paralleling, and comprehensive protection.
The USB to I2C interface is used for communicating between a digital power management device (like the ADP1043A) and the configuration software that runs on a computer. It also supplies 5V and 0.5A to power up the daughter card / evaluation boards.
This same USB to I2C interface connector is used for the ADP1043A, ADP1047, ADP1048, and other digital power management devices.Features
