Page 5: Introduction
Using the UCC25630-1EVM-291 Introduction This EVM, UCC25630-1EVM-291, is used to help evaluate the UCC256301 LLC control device in digital TV SMPS, AC-DC power adapter, LED lighting, etc. applications and then to aid their design. The EVM is a standalone LLC resonant half-bridge DC-DC power converter. The EVM, UCC25630-1EVM-291, can be used as it is delivered without additional work to evaluate an LLC resonant half-bridge DC-DC converter. -
