ROHM BM2P121X | Demoboard BM2P121X-EVK-001

Description

The BM2P121X-EVK-001 evaluation board outputs 12 V voltage from the input of 90 Vac to 264 Vac. The output current supplies up to 0.75 A. The BM2P121X which is PWM method DC/DC converter IC built-in 650 V MOSFET is used. The BM2P121X contributes to low power consumption by built-in a 650 V starting circuit. Built-in current detection resistor realizes compact power supply design.Current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response. The switching frequency is 65 kHz in fixed mode. At light load, frequency is reduced and high efficiency is realized. Built-in frequency hopping function contributes to low EMI. Low on-resistance 1.5 Ohm 650 V MOSFET built-in contributes to low power consumption and easy design.
