BM2P249TF-EVK-001: 3W, 24V @ 125mA, 90 ~ 264VAC in

Summary

The BM2P249TF-EVK-001 evaluation board outputs 24 V voltage from the input of 90 Vac to 264 Vac. The output current supplies up to 0.125 A. BM2P249TF which is PWM method DC/DC converter IC built-in 650 V MOSFET is used. The BM2P249TF contributes to low power consumption by built-in a 650 V starting circuit. Built-in current detection resistor realizes compact power supply design.

Current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response. The switching frequency is 100 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 9.5 Ω, 650 V MOSFET built-in contributes to low power consumption and easy design.
