5.5W Dual Output Industrial Isolated Flybuck Reference Design
Description
PMP20330 is an isolated Flybuck converter utilizing the LM5160 for industrial applications. This design has a minimum operating input voltage of 18V and a maximum input voltage of 31V. The design is capable of sourcing 1A continuous current at 3.3Vout: and 0.5A continuous current at 5Vout. Switching frequency is set to 200kHz. A Wurth transformer 750316561 is used for this design.
Features
- 18V to 31Vin: 7.35V primary output: secondary outputs: +3.3V @ 1A: +5V @ 0.5A – IC capable of 4.5V to 65V inputPrimary side regulation without opto: good regulation: within +/-5%No loop compensation required/fast transient responseLow BOM count and cost: compact solution sizeNo RC snubber at primary winding
