isolation fly-back converter pwm method output 48 w 24 v
the bm2p016t-evk-004 evaluation board outputs a 24v voltage from an input of 90vac to 264vac. the output current provides up to 2.0a. the bm2p016t pwm type dc / dc converter ic with 650v mosfet is used.
- the bm2p016t contributes to low power consumption by incorporating a 650v 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 65khz. at light loads, frequency reduction achieves high efficiency.
- built-in frequency hopping function contributes to low emi. the low on-resistance 1.4ω · 650v 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.
