the bm2p141x-evk-001 evaluation board outputs 14v voltage from the input of 90vac to 264vac. the output current supplies up to 0.715a. the bm2p141x which is pwm method dc/dc converter ic built-in 650v mosfet is used.

• the bm2p141x contributes to low power consumption by built-in a 650v starting circuit. built-in current detection resistor realizes compact power supply design.
• current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response.
• the switching frequency is 65khz 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 1.5ω 650v mosfet built-in contributes to low power consumption and easy design.the bm2p141x contributes to low power consumption by built-in a 650v starting circuit. built-in current detection resistor realizes compact power supply design.
