TDHBG1200DC100: 1.2 kW Half-bridge Evaluation Board
Introduction
The TDHBG1200DC100 half-bridge evaluation board provides the elements of a simple buck or boost converter, using the
Transphorm Daughter Card TDHB-65H070L-DC for basic study of switching characteristics and efficiency achievable with
Transphorm’s 650V GaN FETs in the standard 8x8 PQFN package. In either buck or boost mode the circuit can be configured for
synchronous rectification. Jumpers allow use of a single logic input or separate hi/lo inputs. The high-voltage input and output
can operate at up to 400Vdc, with a power output of up to 1.2kW. The inductor provided is intended for efficient operation at
100kHz, although other inductors and other frequencies may be easily used.
The TDHBG1200DC100-KIT is for evaluation purposes only.
