UCC28740D Information
- UCC28740 Constant-Current Flyback Controllers
- Texas Instruments UCC28740 Constant-Current Flyback Controllers are an isolated-flyback power-supply controller that provides Constant-Voltage (CV) using an optical coupler to improve transient response to large-load steps. Constant-Current (CC) regulation is accomplished through Primary-Side Regulation (PSR) techniques. These devices process information from opto-coupled feedback and an auxiliary flyback winding for precise high-performance control of output voltage and current. An internal 700V start-up switch, dynamically controlled operating states, and a tailored modulation profile support ultra-low standby power without sacrificing start-up time or output transient response. Control algorithms in the UCC28740 allow operating efficiencies to meet or exceed applicable standards. The UCC28740EVM-525 Evaluation Module is a 10W off-line discontinuous mode (DCM) flyback converter that provides constant-voltage (CV) and constant-current (CC) output regulation.
