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.
