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.
BM2P016Twhich isPWMmethod DC/DCconverterIC built-in 650VMOSFETisused.
TheBM2P016Tcontributestolow powerconsumptionbybuilt-ina 650 Vstartingcircuit.
Current mode control imposes currentlimitationon everycycle,providingsuperiorperformancein bandwidthandtransientresponse.The switching
frequencyis 65 kHz infixed mode.At light load, frequency is reduced and high efficiency is realized.Built-infrequency hopping function contributes
to lowEMI. Lowon-resistance1.4 Ω 650VMOSFET built-incontributes to lowpowerconsumptionandeasydesign.
Theflywheeldiodeisafastrecoverydiodeof6A/600V RF601TDNZ,contributingtolowpower consumption.
Theconduction/ radiation emission testis basedonCISPR 22 Class Bwithbest EMIdesign.
