non-isolation buck converter pwm method output 2.6 w 15 v
the bm2p159t1f-evk-001 evaluation board outputs 15v voltage from the input of 90vac to 264vac. the output current supplies up to 0.175a. bm2p159t1f which is pwm method dc/dc converter ic built-in 650v mosfet is used.
- the bm2p159t1f 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 100khz 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 9.5ω 650v mosfet built-in contributes to low power consumption and easy design.
