REFACDC020 - Reference Design

Non-Isolation Buck Converter PWM method Output 15 W 15 V

The BM2P016-EVK-001 evaluation board outputs a 15V voltage from an input of 90Vac to 264Vac. The output current provides up to 1.0A.The BM2P016 PWM type DC/DC converter IC with 650V MOSFET is used.

  • The BM2P016 contributes to low power consumption by incorporating a 650V withstand voltage startup circuit.
  • Using current mode control, cycle-by-cycle current limiting provides excellent performance in bandwidth and transient response.
  • The switching frequency is fixed at 65kHz. At light loads, frequency reduction achieves high efficiency.
  • Built-in frequency hopping function contributes to low EMI. The low on-resistance 1.4Ω· 650V withstand voltage MOSFET is built in, contributing to low power consumption and easy design.
  • The optimized EMI design complies with CISPR 22 Class B for noise terminal voltage / radiation emission testing.
