The evaluation board features an isolated full bridge topology with full bridge secondary side rectification operating at 125KHz switching frequency. Its rated output is 12V, 20A with an input ranging from 38-60VDC.
The evaluation board features the ADP1055 digital controller as the main controller for providing various functions such as PWMs, voltage and current sensing, feedback, etc. It also provides protection features such as OCP, OVP, and OTP.
Advanced features such as black-box, active snubber, constant current mode, double update rate, digital compensation are self contained in the ADP1055.
ADP1055 Daughter Board development Kit allows users to quickly and easily retrofit the ADP1055 into existing design solutions.
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.
