1FEATURES DESCRIPTION
The UCC29910A Buck Power Factor Correction• Buck Power Factor Correction for High (PFC) controller provides a relatively flatEfficiency Across Line high-efficiency performance across universal line for• Low Off-Line Startup Current, With SmartStart designers requiringa high power factor (>0.9) andAlgorithm for Fast Startup With Soft-Start wishingto meet the requirementsof IEC 61000-3-2.• Compatible With Resistiveor Pass Transistor Based ona buck topology, inherent inrush currentFed Startup from the AC Line limiting eliminates the need for additional• Low Power SmartBurst Mode for Standby and components. Witha typical bus voltageof 84V, theLight-Load Conditions topologyis ideally suited for use with low voltage
stress downstream regulation/isolation power trains,• Current Sense Inputs for PFC control and
such as half-bridge stages controlled by theOverload Protection
UCC29900, (Texas Instruments Literature Number,• Line Sense UVLO SLUS923). This combination offers low• Sense and Drive Control for External Startup common-mode noise generation allowing reducedDepletion Mode FET filtering and exceptionally high conversion efficiency.• Latching Fault Input Pin The UCC29910A incorporates AC line UVLO and
controlled soft start for fast start-up. EnhancedAPPLICATIONS light-load efficiencyis achieved through advanced• High Efficiency AC-DC Adapters management algorithms for best-in-class no-load and Low Profile and High Density Adapters light-load performance.
