Overview
The XDPS21081XUMA1 is a digital flyback controller IC from Infineon Technologies, designed for AC-DC conversion with step-up and step-down capabilities. It operates within a supply voltage range of 7.2V to 20.5V and supports switching frequencies between 23kHz and 139.1kHz. The device features a PG-DSO-12-20 package and includes control characteristics such as current limit, dead time control, enable, frequency control, and soft start. It is rated for an operating temperature range of -25°C to 125°C TJ.
Feature Summary
- Supports low line quasi-resonant (QR) and high line fixed-frequency resonant (FQR) zero-voltage switching (ZVS) modes.
- Features configurable ZVS enabled by line voltage and low-side ZVS MOSFET gate control.
- Includes ZVS optimization per variable output voltage.
- Provides integrated current limit, dead time control, and soft start functions.
Applications
- AC-DC power supplies
- Flyback converter designs
- Industrial power systems
Procurement Notes
Verify the component status before procurement, as some sources indicate this part may be obsolete or no longer manufactured. Confirm the specific datasheet version and package details (PG-DSO-12-20) against your design requirements. Ensure compatibility with your intended switching frequency and voltage ranges. Check for any product change notifications (PCN) that might affect performance or reliability. Consult official Infineon documentation for the most current availability and technical specifications.
Selection Notes
Select this controller for applications requiring efficient flyback conversion with ZVS capabilities. Consider its support for both QR and FQR modes for optimized performance across different line voltages. Evaluate the need for configurable ZVS and variable output voltage optimization. Ensure the operating temperature range meets your environmental requirements. Compare with other digital flyback controllers if PFC integration is needed.
Part Context
The XDPS21081XUMA1 belongs to Infineon's XDP series of digital power management ICs. These controllers are designed for high-efficiency AC-DC and DC-DC conversions. The series typically integrates advanced digital control algorithms to enhance performance and reduce external component count. This specific model focuses on flyback topologies with resonant switching features.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Verify cross-compatibility with other Infineon XDP series controllers or similar flyback controllers from other manufacturers based on pinout, electrical specifications, and control features.
