Isolation Fly-back Converter PWM method Output 22.5W 15V
BM2P016T Reference Board
BM2P016T-EVK-002
The BM2P016T-EVK-002 evaluation board outputs 15V voltage from the input of 90Vac to 264Vac. The output current supplies up to 1.5A.
BM2P016T which is PWM method DC/DC converter IC built-in 650V MOSFET is used.
The BM2P016T contributes to low power consumption by built-in a 650 V starting circuit.
Current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response. The switching
frequency is 65 kHz in fixed mode. At light load, frequency is reduced and high efficiency is realized. Built-in frequency hopping function contributes
to low EMI. Low on-resistance 1.4 Ω 650 V MOSFET built-in contributes to low power consumption and easy design.
The flywheel diode is a fast recovery diode of 6A/600 V RF601TDNZ, contributing to low power consumption.
The conduction / radiation emission test is based on CISPR 22 Class B with best EMI design.

■<High Voltage Safety Precautions>
◇ Read all safety precautions before use
Please note that this document covers only the BM2P016T-Z evaluation board
(BM2P016T-EVK-002) 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
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.
