REFACDC028 - Reference Design

The BM2P016T-EVK-004 evaluation board outputs a 24V voltage from an input of 90Vac to 264Vac. The output current provides up to 2.0A. The BM2P016T PWM type DC / DC converter IC with 650V MOSFET is used.

• The BM2P016T 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.
