This reference design is a wide input, 12-V and 2-A output isolated flyback converter using LM5155. The switching frequency is 250 kHz and the peak efficiency of the system is 89.19% at 24-V input. The load regulation in the input range is within ±0.5%. Peak-to-peak ripple of the output is within 296 mV under load transient from 1 A to 2 A with a slew rate of 1 A/us.
