isolation fly-back converter pwm method output 48 w 12 v

the bm2p016t-evk-003 evaluation board outputs a 12v voltage from an input of 90vac to 264vac. the output current provides up to 4.0a. the bm2p016t pwm type dc / dc converter ic with 650v mosfet is used.


  • the bm2p016t contributes to low power consumption by incorporating a 650v withstand voltage startup circuit.
  • using current mode control, cycle-by-cycle current limiting provides excellent performance in bandwidth and transient response.
  • the switching frequency is fixed at 65khz. at light loads, frequency reduction achieves high efficiency.
  • built-in frequency hopping function contributes to low emi. the low on-resistance 1.4ω · 650v withstand voltage mosfet is built in, contributing to low power consumption and easy design.
  • the optimized emi design complies with cispr 22 class b for noise terminal voltage / radiation emission testing.
