Infineon Technologies EVAL_HB_BC_1EDN8550B Evaluation Board

Infineon EVAL_HB_BC_1EDN8550B Half-bridge Buck Converter Evaluation Board offers a platform for demonstrating the EiceDRIVER™ 1EDN TDI, a 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) that are existing between the driver and the microcontroller ground potentials. The driving issues 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. The EVAL_HB_BC_1EDN8550B enables an evaluation of the proper 1EDN TDI driving with AC and DC ground shifts generated on purpose. The 1EDN TDI as a high-side driver used in a half-bridge design is designed to provide further evidence of its DC ground shift robustness.
