Product Details

The evaluation board features an isolated full bridge topology operating at 100KHz switching frequency. Its output is rated at deliver 12V, 9A with an input ranging from 36-60VDC. The board features the ADP1043A digital controller as the main controller for providing various functions such as current PWMs and OrFET control. It also provides protection features like OCP and OVP.


  • Full bridge topology with advanced volt second balance to eliminate blocking capacitor
  • High efficiency (>87%)
  • Low component count
  • Protection features for input and output current.
  • Programmable responses to faults
  • Digital trimming
  • Test points for key features like gate-source voltages, synchronous rectifiers, transformer primary winding etc.

Software and Tools

  • ADP1043A Software
    This software is used to program the ADP1043A. It is truly graphic and interactive. Power design engineers with no prior programming experience can use the software to monitor and quickly adjust functions like PWM timings, frequency, filter settings, protection limits, etc.

Supporting Boards

ADP1043A Daughterboard Development Kit allows users to quickly and easily retrofit the ADP1043A into existing design solutions.

  • Standalone daughterboard for customer design retrofitting into almost any existing customer application design
  • Used in any design and run from 5V
  • Size: 25mm x 40mm

Adapters and Interposers

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.
