XDPL8219XUMA1

Overview

The XDPL8219XUMA1 is a digital flyback controller IC from Infineon Technologies, designed for AC-DC LED lighting and power supply applications. It integrates power factor correction (PFC) with a target PFC greater than 0.9 and standby power below 100 mW. The device supports single-stage operation with primary-side regulation (PSR) or secondary-side regulation (SSR). Key electrical parameters include a switching frequency of 66 MHz, an output voltage range of 10 V to 450 V, and an output current capability of 108 mA. It operates within a temperature range of -40°C to +150°C and is housed in an 8-pin PG-DSO package.

Feature Summary

• Detects input voltage type (AC or constant DC) and adjusts the proprietary voltage mode pulse modulator accordingly to optimize system performance.
• Integrates digital power control to reduce external component count while maintaining high efficiency across a wide load range.
• Supports UART communication interface for configuration and monitoring in LED lighting and AC-DC supply systems.

Applications

• High power factor flyback converters for LED lighting
• AC-DC power supplies requiring low standby power
• Single-stage controllers with primary-side regulation

Procurement Notes

Verify the specific ordering suffix XUMA1 to confirm the reel packaging format and moisture sensitivity level. Ensure compatibility with the required PG-DSO-8 footprint during PCB layout. Cross-reference the manufacturer part number XDPL8219XUMA1 against official Infineon documentation to validate the revision status and functional specifications before integration into the design.

Selection Notes

Select this component for designs requiring integrated PFC and flyback control in a compact form factor. It is suitable for applications demanding high efficiency and fast dynamic response to load changes. Consider the 66 MHz switching frequency for magnetics size optimization. Verify that the 108 mA output current meets the gate drive requirements for the external power switch.

Part Context

This part belongs to Infineon's XDPL series of digital flyback controllers. It is related to the XDPL8210, which shares similar topology but may differ in specific feature sets or regulatory compliance. The series focuses on reducing system cost through component minimization and digital control flexibility for smart LED lighting and IoT power conversion.
