Half-bridge buck converter evaluation board using the EiceDRIVER™ 1EDN TDI

This evaluation board is intended to show the strengths of the EiceDRIVER™ 1EDN TDI (1EDN8550B or 1EDN7550B), family of single-channel low-side gate drivers with innovative truly differential inputs (TDI) concept.

The TDI concept is intended to overcome driving issues when DC offset (DC GND shift) or AC voltage drops (AC GND shift) are existing between the driver and the microcontroller ground potentials. Common situations characterized by DC and AC GND shifts are, respectively, the driving of high-side devices and the driving in noisy environments with significant stray inductance on the ground path.

This evaluation board allows to evaluate the proper 1EDN TDI driving with AC and DC ground shifts generated on purpose. The half-bridge design using the 1EDN TDI as high-side driver is intended to provide further evidence of its DC ground shift robustness.

Summary of features

  • 48V half-bridge buck converter tested up to 60W
  • Integrated section to generate and regulate the DC GND shift
  • Possibility to easily regulate the AC GND shift
  • Possibility to compare the 1EDN TDI and standard low side driver in GND shift situation

Summary of benefits

Easy platform to show the following advantages when using 1EDN TDI:

  • Immunity to DC and AC GND shifts
  • Separate high-side and low-side driving for layout flexibility and cost reduction
