flyback type pwm mode, isolated 12v 1.0a 12w bm2p0363f evaluation board
this evaluation board output an isolated 12 v voltage, output from a 90 vac to 264 vac input. the maximum output power can output 12 w. bm2p0363f which is pwm method dc/dc converter ic built-in 650 v mosfet is used. low on-resistance 3.0 ω 650 v mosfet built-in contributes to high efficiency (86.7 % typ). pwm controller for ac / dc power supplies, the bm2p0363f provides the optimum system for all products with outlets.
