UCC28C41P

DC DC Switching Controllers Overview

The UCC28C41P is a BiCMOS low-power current-mode PWM controller from Texas Instruments. It supports Boost, Flyback, and Forward topologies with a single output. The device operates within an input voltage range up to 20 V and features a fixed switching frequency of 1 MHz. It offers a maximum duty cycle of 50% and includes undervoltage lockout thresholds at 7 V/6.6 V. The component is housed in an 8-DIP package and is designed for industrial applications.

DC DC Switching Controllers Feature Summary

• Current-mode control architecture for stable regulation
• Low-power BiCMOS technology for efficient operation
• Supports multiple converter topologies including Boost and Flyback
• Integrated undervoltage lockout protection

DC DC Switching Controllers Applications

• Industrial power supply designs
• Flyback converter implementations
• Boost converter circuits
• Forward converter systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'P' indicates the PDIP-8 package variant. Confirm RoHS compliance status as some sources indicate non-compliance or lack of information. Ensure the supplier provides original manufacturer documentation to validate authenticity and lot traceability before procurement.

DC DC Switching Controllers Selection Notes

Select this component when a 50% maximum duty cycle is sufficient for the application topology. It is suitable for industrial environments requiring low quiescent current. Compare against the UCC28C44 series if automotive qualification (AEC-Q100) or higher temperature ratings are required instead of standard industrial specifications.

DC DC Switching Controllers Part Context

This part belongs to the UCC28C4x family of low-power current-mode PWM controllers. It shares functional similarities with the UCC28C40 and UCC28C44 but differs in package options and specific qualification levels. The UCC28C41 is positioned for general industrial use rather than automotive-grade requirements.

DC DC Switching Controllers Replacement Considerations

Check for UCC28C41DR or UCC28C41DGK as alternative packages within the same electrical specification. Verify compatibility with existing PCB footprints if transitioning from DIP to surface-mount variants.
