XDPS2221XUMA1

XDPS2221XUMA1 is a PFC + hybrid-flyback - combo controller is a highly integrated device combining a multimode ac-dc PFC controller and a multimode dc-dc hybrid-flyback controller. The integration of PFC and hybrid-flyback into a single package enables the reduction of external bill of material components and optimizes the system performance by harmonized operation of the two stages. Application includes ultra high power density chargers / adapters.

• Digital combo controller for PFC-boost and dc-dc hybrid-flyback in DSO-14 (150mil) package
• Novel ZVS hybrid-flyback (asymmetrical half-bridge) topology for ultra-high system efficiency
• Integrated gate driver supporting GaN and Si switches
• 600V high voltage start-up cell for fast VCC charging and active X-capacitor discharge
• Burst mode operation control for lowest no-load stand-by power
• Configurable parameters for protection modes and system performance
• Configurable PFC QRM operation for improved average efficiency
• Pulse skipping for improved light load efficiency
• Automatic PFC disable/enable-control depending on operating conditions
• Junction operation temperature range from -40 to 125°C, PG-DSO-14 package
