refacdc046reference design / application evaluation kit | rohm co., ltd.-凯发k8一触即发
flyback type pwm mode isolated 12v 1.4a 16.8w
this reference design uses bm2p13b1j.
- this evaluation board outputs an isolated voltage of 12 v from an input of 90 vac to 264 vac, and the maximum output current is 1.4 a.
- bm2p13b1j-z which is pwm method dc/dc converter ic built-in 730 v mosfet is used.
- built-in the low on resistor (1.0 ω) and high voltage tolerant mosfet (730 v) make designs easy.
- pwm controller for ac / dc power supplies, the bm2p13b1j provides the optimum system for all products with outlets.
