This LM5160 Fly-Buck application example is designed to operate from a 24-V DC supply with line variations from 18 V to 32 V. The example provides a space-optimized and efficient 12-V isolated output solution with secondary load current capability from 0 mA to 400 mA. The primary side remains unloaded in this application. The switching frequency is set at 300 kHz (nominal). This design achieves greater than 88% peak efficiency.
