refacdc045reference design / application evaluation kit | rohm co., ltd.-ag凯发旗舰厅
flyback type pwm mode isolated 5v 2a 12v 1a non-isolated 18.7v 0.1a 24w
this reference design uses bm2p061mf.
- the evaluation board outputs an isolated 5 v voltage, an isolated 12 v voltage and a non-isolated 18.7 v output from a 90 vac to 264 vac input, the maximum output power can output 24w.
- bm2p061mf which is pwm method dc/dc converter ic built-in 650 v mosfet is used.
- low on-resistance 1.0 ω 650 v mosfet built-in contributes to high efficiency (84.5 % typ).
- pwm controller for ac / dc power supplies, the bm2p061mf provides the optimum system for all products with outlets.
