non-isolation buck converter pwm method output 7.5w 15v
the bm2p0161-evk-001 evaluation board outputs 15v voltage from the input of 90vac to 264vac. the output current supplies up to 0.5a. bm2p0161 which is pwm method dc/dc converter ic built-in 650v mosfet is used.
- the bm2p0161 contributes to low power consumption by built-in a 650 v starting circuit.
- current mode control imposes current limitation on every cycle, providing superior performance in bandwidth and transient response. the switching frequency is 65 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 1.0 ω 650 v mosfet built-in contributes to low power consumption and easy design.
- the flywheel diode is a fast recovery diode of 3a/600 v rfn3bm6s, contributing to low power consumption.
- the conduction / radiation emission test is based on cispr 22 class b with best emi design.
