TDHBG1200DC100-KIT: 1.2 kW Half-Bridge Buck 2:1 or Boost 1:2

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.
