24v 2a output, bm1p061fj evaluation board
reference board. it used to pwm method dc/dc converter controller ic bm1p061fj. bm1p061fj is including 650v high voltage starter, for low stand-by power. output voltage control method is used current mode regulation, therefore it can used cycle by cycle current limit. it is achieved quick response of dynamic load changing situation. switching frequency is fixed 65 khz. light load situation has frequency decrease function that recognize high efficiency. switching frequency jitter function is included for low emi. various functions are included for safety, soft start, frequency burst mode, vcc ovp, output olp and brown out.
- pwm frequency : 65khz, 100khz
- pwm current mode method
- frequency hopping function
- burst operation / frequency reduction function when load is light
- built-in 650v start circuitrohm bm1p061fj-evk-001 is from wide input voltage (90vac～264vac) to output 24v 2a max.
- constant voltage
