Infineon Technologies AG DC DC Switching Controllers XDPS21081XUMA1

The XDPS21081XUMA1 is a digital PWM controller designed for high-density adapter applications, utilizing a Forced Quasi-resonant Zero Voltage Switching (ZVS) flyback topology. It features an integrated 600 V startup cell for rapid startup and direct bus voltage sensing, ensuring efficient operation across a wide input voltage range of 85 to 264 VAC. The controller supports multi-mode operation, including low line QR and high line FQR ZVS modes, and guarantees discontinuous conduction mode (DCM) operation. Key features include adaptive current limitation for variable output voltage, built-in protection modes such as brown-in and brownout detection, and a one-pin UART interface for configuration. The device is compliant with RoHS and halogen-free standards, making it suitable for environmentally conscious designs. The XDPS21081XUMA1 is qualified for industrial applications according to JEDEC standards, ensuring reliability in demanding environments. This product is ideal for engineers seeking a robust and efficient solution for power management in adapter and charger designs.
