ROHM BM2P016 | Demoboard BM2P016-EVK-001

Description

The BM2P016-EVK-001 evaluation board outputs a 15 V voltage from an input of 90 Vac to 264 Vac. The output current provides up to 1.0 A. The BM2P016 PWM type DC / DC converter IC with 650 V MOSFET is used. The BM2P016 contributes to low power consumption by incorporating a 650 V 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 65 kHz. At light loads, frequency reduction achieves high efficiency. Built-in frequency hopping function contributes to low EMI. The low on-resistance 1.4 Ohm 650 V 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.
