isolation fly-back converter pwm method output 22.5w 15v

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.
