REFACDC022 - Reference Design

This evaluation board’s output voltage is 5V for an input voltage 90Vac to 264Vac and the maximum output current is 0.5A. The BM2P26CK-Z is an AC/DC flyback converter in PWM Mode with integrated 800V MOSFET.

• The built-in 650V startup circuit in BM2P26CK-Z contributes to low power consumption.
• Current is restricted in each cycle and excellent performance is achieved in bandwidth and transient response since current mode control is utilized.
• The switching frequency is operating at 100kHz. At light load, the switching frequency is reduced and high efficiency is achieved.
• A built-in frequency hopping function contributes to low EMI. Built-in the low on resistor (6.0Ω) and high voltage tolerant MOSFET (800V) make designs easy.
• The BMP2P26CK-Z has reached (achieved) IEC62368-1 standard authorization.
• This evaluation board is compliant with CISPR22 Class B which is the test of the noise pin voltage and emission by an optimum EMI design.
