ZHCSFE2A August 2016 – November 2017 LM5161-Q1
PRODUCTION DATA.
The LM5161-Q1 Fly-Buck application example is designed to operate from a nominal 48-V DC supply with line variations from 36-V to 72-V. This example provides a space-optimized and efficient 12-V isolated output solution with secondary load current capability from 0-A to 800 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.
