Original Press Release:
Richardson RFPD Introduces New Auxiliary Power Supply Evaluation Board for SiC MOSFET from Wolfspeed
Single-end flyback converter design delivers 48 W of power utilizing 1700 V SiC MOSFET in a low-inductance surface mount D2PAK to reduce total cost and simplify design
Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new evaluation board from Wolfspeed, a Cree Company.
The CRD-060DD17P-2 is a demonstration board for a single-end flyback converter design with built with Wolfspeed’s commercially-available 1700 V SiC MOSFET.
The 48 W experimental reference design demonstrates how the 1700 V SiC MOSFET can reduce total cost and simplify the design of auxiliary power supply. It replaces the more common, but more complicated, silicon-based two-switch flyback topology, while successfully supporting a wide input voltage range (300 V to 1000 V). An active start-up circuit is also introduced to achieve less start-up losses with faster start-up time.
The design utilizes Wolfspeed’s C2M1000170J, which is available in a 7LD2PAK surface mount package that combines a small footprint with a wide creepage distance—7mm between drain and source. By moving to the surface mount package, design engineers can achieve economical thermal designs without the need for heat sink on the MOSFET. The addition of a heat sink enables the same design to reach 58 W of output power.
The C2M1000170J features high blocking voltage with low RDS(on), low parasitic inductance, ultra-low drain gate capacitance, and a separate driver source pin. It is easy to parallel and simple to drive, and it is ideally suited for auxiliary power supplies, switch mode power supplies, and other applications involving high-voltage capacitive loads.
