QUICK START
GUIDE
100 W Auxiliary Power Supply Eval Board
BD7682FJ-LB-EVK-302
This quick start guide will help you understand the connection, operating Instructions and important notices and warnings that need to be carefully
reviewed prior to use of the board (Figure 1). For further information please refer to the user guide (No. 63UG067E Rev.001) and the BD7682FL-LB
Application Note (No. 60AN060E Rev.001) which can also be obtained from ROHM's webpage.
The BD7682FJ is an AC/DC quasi-resonant flyback controller IC from ROHM Semiconductor and offers an Auxiliary Power Supply Solution if
combined with the 1700 V SiC MOSFET (SCT2H12NZ). The BD7682FJ and SCT2H12NZ combined together have been used to develop an
isolated 100 W 24 V output auxiliary power solution with a very accurate voltage regulation.

Important Notice
This evaluation board is intended for product evaluation in a research and development context only and is not intended for resale to end
consumers and it is not authorised for end customer or household use. This board may not comply with CE or similar standards (including, but not
limited to the EMC directive 2004/EC/108) and may not fulfil other requirements of the country it will be operated in by the user. The user shall ensure
that the evaluation board will be handled in a way that is compliant with all the standards and regulations in the country it will be operated in.
The evaluation board provided here has only been subjected to functional testing under typical load conditions. The design of this evaluation board
is tested by ROHM only as described in the user guide for this board. The design is not qualified in terms of safety requirements, manufacturing and
operation over the entire operating temperature range or lifetime.
This evaluation board may only be used by authorised personnel that is properly trained in recognizing and dealing with the dangers of
testing high voltage equipment and generally experimenting with high voltage circuits. Ensure you review this user guide as it contains
important safety warnings. At all times, follow the applicable safety rules for dealing with high voltages. Do not connect or disconnect any wires or
probes to the evaluation board, while it is connected to a power supply. Take care that capacitors on the board have discharged fully before touching
any part of the board. Always place the evaluation board under appropriate covers, such as in a Perspex box, to protect against accidental touching
of high voltage parts BEFORE applying a voltage supply to the board.
