REFACDC010 - Reference Design
Non-Isolation Buck Converter PWM method Output 10W 16.5V
The BM2P161W-EVK-001 evaluation board outputs 16.5V voltage from the input of 90Vac to 264Vac. The output current supplies up to 0.6A. BM2P161W which is PWM method DC/DC converter IC built-in 650V MOSFET is used.
- The BM2P0161 contributes to low power consumption by built-in a 650V starting circuit. Built-in current detection resistor and feed-back circuit realize 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 1.9Ω 650V MOSFET built-in contributes to low power consumption and easy design.
- The flywheel diode is a fast recovery diode of 3A/600V RFN3BM6S, contributing to low power consumption.
- The conducted emission test is based on CISPR 22 Class B with best EMI design.
