XDPS21071XUMA1

Overview

The XDPS21071XUMA1 is a digital front-end regulator controller optimized for flyback converters. It integrates a digital core with an ARM Cortex-M0 architecture to manage power conversion processes. The device supports multi-mode operation, including forced frequency and resonant modes, to enhance efficiency across varying load conditions. It functions as a step-up/step-down DC-DC controller with positive output configuration. The component is designed for medium-power applications, typically achieving efficiencies between 85% and 92%. It utilizes a PG-DSO-12-20 package for surface-mount installation.

Feature Summary

• Integrates a digital kernel with an ARM Cortex-M0 architecture for advanced control capabilities
• Optimized for flyback converter topologies with multi-mode digital and forced frequency resonant operation
• Provides transistor driver output for gate control in switching applications

Applications

• Offline switch-mode power supplies (SMPS)
• Flyback converter designs
• Medium-power AC-DC adapters

Procurement Notes

Verify the current lifecycle status before integration, as the component is marked as Not For New Designs. Confirm package availability and datasheet revisions directly with Infineon Technologies or authorized distributors. Ensure design compatibility with existing thermal and electrical constraints associated with legacy product lines.

Selection Notes

Select this controller for flyback applications requiring digital flexibility and high efficiency. Consider its suitability for medium-power ranges up to approximately 73W or 105W depending on topology. Evaluate the need for ARM Cortex-M0 programmability against fixed-function alternatives. Verify package dimensions and pinout compatibility with PCB layout requirements.

Part Context

This part belongs to the XDP™ digital power controller family, which combines digital processing with analog power management. It is related to other CoolSET™ PWM controllers like the XDPS2211 series but offers distinct digital control features. The component serves as a specialized solution for efficient offline power conversion compared to standard analog PWM ICs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is designated 'Not For New Designs', alternative selection should focus on newer generations within the XDP or CoolSET families that offer updated lifecycle support and similar functional specifications.
