UCC28056 Key Features
- 1 Ultra-low no-load input power enables < 80-mW standby power at 230 VAC in PFC+LLC system
- Excellent light load efficiency and high efficiency over wide range of load due to multi-mode TM and DCM control
- Enables low system cost through FET Drain valley synchronized turn-on which eliminates need for second winding on the bo
- Enables pliance to green power standards without disabling PFC
- EuP Lot 6 Tier 2, CoC Ver. 5 Tier 2, Energy Star Ver. 6.1, DoE Level VI
- Burst mode with soft-entry and soft-exit periods enables ultra-low audible noise output
- Enhanced Error Amplifier, responds rapidly to load steps without degrading input current distortion
- User adjustable valley delay ensures valley switching
- Low start-up current consumption (<46 µA)
- Wide VCC range 8.5 V to 34 V
