XDPS2221E The XDP™ XDPS2221E PWM combines multimode AC-DC PFC and DC-DC hybrid-flyback controllers, ideal for wide output voltage range designs.
Überblick
XDP™ XDPS2221E is a digital combo controller with configurable parameters for protection modes and maximized system performance. The novel ZVS hybrid-flyback (HFB, known also as asymmetrical half-bridge) topology enables ultra-high system efficiency.
The integration of PFC and hybrid-flyback into a single package optimizes the system performance by harmonized operation of the two stages and reduces the external bill of material components.
