Texas Instruments UCC28730EVM-552 Evaluation Module

Texas Instruments UCC28730EVM-552 Evaluation Module is a 10W off-line discontinuous mode (DCM) flyback converter that provides constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler. The primary side controller detects a wake-up signal from the secondary side voltage droop monitor UCC24650 for improved transient response to large load steps. The Texas Instruments UCC28730EVM-552 demonstrates how the UCC28730 can provide ultra-low standby power without sacrificing start-up time or output transient response with an internal 700V start-up switch, dynamically controlled operating states, and a tailored modulation profile.
