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
