isolation fly-back converter pwm method output 24w 12v

rohm bm2p0161-evk-003 is from wide input voltage (90vac to 264vac) to output 12v 2a max. constant voltage reference board. it used to pwm method dc/dc converter ic bm2p0161.


  • bm2p0161 is including 650v high voltage power mosfet and starter. the starter realize low stand-by power.
  • output voltage control method is used current mode regulation, therefore it can used cycle by cycle current limit. quick response in dynamic load changing is achieved.
  • switching frequency is fixed 65khz. light load situation has frequency decrease function for higher efficiency.
  • switching frequency jitter function enables lower emi operation.
  • various functions are included for safety, soft start, frequency burst mode, vcc ovp, output olp and thermal shut down.
