The UCC28730EVM-552 evaluation module from Texas Instruments is a 10-W 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 EVM demonstrates how the UCC28730 can provide ultra-low standby power without sacrificing start-up time or output transient response with an internal 700-V start-up switch, dynamically controlled operating states, and a tailored modulation profile. It operates with an input voltage range of 85 to 265 VAC and delivers 10W output power at 2A output current with a switching frequency of 28 kHz.
The board achieves less than 5mW of no-load power consumption. Primary side regulation eliminates the need for an opto-coupler, and wake-up detection helps minimize no-load switching frequency and output capacitance. The board is fully populated and includes the UCC28730 primary side flyback controller and UCC24650 secondary side wake-up monitor.
