1 User s Guide AC/DC Converter NonIsolation Buck Converte PWM method Output 6W 2V BM2P6 Referencee Board BM2P6EVK2 The BM2P6EVK2 evaluation board outputs 2V voltage from the input of 9Vac to 264Vac. The output current supplies up to.5a. BM2P6 which is PWM method DC/DC conve erter IC builtin 65V MOSFET is used. The BM2P6 contributes to low power consumption by builtin a 65 V starting circuit. Curre ent mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transientt response. The switching frequency is 65 khz in fixed mode. At light load, frequency is reduced and high efficiency is realized. Builtin frequency hopping function contributes to low EMI. Low onresistance. Ω 65 V MOSFET builtin contributes to low power consumption and easy design. The flywheel diode is a fast recovery diode of 3A/ /6 V RFN3BM M6S, contributing to low power consumption. The conduction / radiation emissio on test is based on CISPR 22 Class B with best EMI design. Electronics Characteristics Not guarantee the characteristics, is representative value.
