High Voltage Safety Precautions
＞
◇
Read all safety precautions before use
Please note that this document covers only the BM1Q104FJ evaluation board
(BM1Q104FJ-EVK-001) and its functions. For additional information, please refer to the
datasheet.
To ensure safe operation, please carefully read all precautions before
handling the evaluation board
Depending on the configuration of the board and voltages used,
Potentially lethal voltages may be generated.
Therefore, please make sure to read and observe all safety precautions described in
the red box below.
Before Use
[1] Verify that the parts/components are not damaged or missing (i.e. due to the drops).
[2] Check that there are no conductive foreign objects on the board.
[3] Be careful when performing soldering on the module and/or evaluation board to ensure that solder
splash does not occur.
[4] Check that there is no condensation or water droplets on the circuit board.
During Use
[5] Be careful to not allow conductive objects to come into contact with the board.
[6] Brief accidental contact or even bringing your hand close to the board may result in
discharge and lead to severe injury or death.
Therefore, DO NOT touch the board with your bare hands or bring them too close to the board.
In addition, as mentioned above please exercise extreme caution when using conductive tools such as
tweezers and screwdrivers.
[7] If used under conditions beyond its rated voltage, it may cause defects such as short-circuit or,
depending on the circumstances, explosion or other permanent damages.
[8] Be sure to wear insulated gloves when handling is required during operation.
After Use
[9] The ROHM Evaluation Board contains the circuits which store the high voltage. Since it stores the
charges even after the connected power circuits are cut, please discharge the electricity after using
it, and please deal with it after confirming such electric discharge.
[10] Protect against electric shocks by wearing insulated gloves when handling.
This evaluation board is intended for use only in research and development facilities and
should by handled only by qualified personnel familiar with all safety and operating
procedures.
We recommend carrying out operation in a safe environment that includes the use of high
voltage signage at all entrances, safety interlocks, and protective glasses.

Operation Procedure
1 Necessary Equipment
(1) AC power supply (90 Vac to 264 Vac, 200 W or more)
(2) Load equipment (5 A at maximum value)
(3) DC voltmeter
2 Connect to Each Equipment
(1) Preset the AC power to 90 Vac to 264 Vac and turn off the power output.
(2) Set the load below the rated current of each output to disable the load.
(3) Connect the N terminal of the power supply to the CN1-1: AC (N) terminal and the L terminal to the CN1-2: AC (L)
terminal with a pair of wires.
(4) Connect load to VOUT terminal from the positive terminal and to GND terminal with a pair of wires.
(5) When connecting a power meter, connect as follows. (For details, refer to the User's Manual of the electricity meter you
are using.)
(6) Connect the positive terminal of the DC voltmeter to VOUT terminal and the negative terminal to GND terminal for
output voltage measurement.
(7) AC power supply switch is ON.
(8) Make sure that the DC voltmeter reading is at the set voltage (20 V).
(9) Electronic load switch is ON.

BM1Q104FJ-EVK-001
Application Circuit
This evaluation board operates in Quasi-Resonant method.
The output (20 V) voltage is monitored by a feedback circuit and feed back to the FB pin of BM1Q104FJ through a opto - coupler.
At startup, the voltage at the VCC pin rises as the voltage is supplied from the VH pin to the VCC pin through the start circuit.
When the VCC pin voltage exceeds the UVLO release voltage of 13.5 V (Typ), the BM1Q104FJ starts operating.
After start of switching, the startup circuit is turned off and it cut the supply from the VH pin, in order to have low power consumption
for instance in standby mode.
