non-isolation buck converter pwm method output 12 w 15 v
the bm2p151x-evk-001 evaluation board outputs 15v voltage from the input of 90vac to 264vac. the output current supplies up to 0.8a. the bm2p151x which is pwm method dc/dc converter ic built-in 650v mosfet is used.
- the bm2p151x contributes to low power consumption by built-in a 650v 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 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 1.5ω 650v mosfet built-in contributes to low power consumption and easy design.
