REFACDC012 - Reference Design
Non-Isolation Buck Converter PWM method Output 10 W 14 V
The BM2P141X-EVK-001 evaluation board outputs 14V voltage from the input of 90Vac to 264Vac. The output current supplies up to 0.715A. The BM2P141X which is PWM method DC/DC converter IC built-in 650V MOSFET is used.
- The BM2P141X contributes to low power consumption by built-in a 650V 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 65kHz 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 1.5Ω 650V MOSFET built-in contributes to low power consumption and easy design.The BM2P141X contributes to low power consumption by built-in a 650V starting circuit.
