The ROHM 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. It is PWM method DC or 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 % type). PWM controller for AC or DC power supplies, it provides the optimum system for all products with outlets
