UCC28C43: Datasheet Typical Application Transformer

Part Number: UCC28C43

In this diagram what does the LP=1.5mH etc. exactly describe? Also, what is the turn ratios?

Hi Handy Andy,

Thanks for your interest in UCC28C43. Lp describes the primary side inductance of the transformer. The turns ratio from primary to secondary is 10:1. The turns ratio from primary to auxiliary is 10:1.
