Infineon Technologies AGXDPS21071XUMA1AC to DC Switching Converters
XDPS21071XUMA1| High-performance flyback controller IC - multi-mode digital, forced frequency resonant
Infineon’s XDPS21071 is the first flyback controller IC in the industry to introduce ZVS (zero-voltage switching) on the primary side to achieve high efficiency with simplified circuitry and economical switches. By driving an external low voltage switch to induce a negative current to discharge the main high voltage MOSFET, switching losses can be reduced further compared to traditional valley switching type of switching schemes. To achieve high efficiency with synchronous rectification, the XDPS21071 multi-mode digital forced-frequency resonant (FFR) flyback controller IC ensures DCM (discontinued conduction mode) operation via valley detection for a safe and robust operation.
