REFACDC026 - Reference Design
Isolation Fly-back Converter PWM method Output 22.5W 15V
The BM2P016T-EVK-002 evaluation board outputs 15V voltage from the input of 90Vac to 264Vac. The output current supplies up to 1.5A. BM2P016T which is PWM method DC/DC converter IC built-in 650V MOSFET is used.
- The BM2P016T contributes to low power consumption by built-in a 650 V starting circuit.
- 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 1.4 Ω 650 V MOSFET built-in contributes to low power consumption and easy design.
- The flywheel diode is a fast recovery diode of 6A/600 V RF601TDNZ, contributing to low power consumption.
- The conduction / radiation emission test is based on CISPR 22 Class B with best EMI design.
