UCC3580D-1

DC DC Switching Controllers Overview

The UCC3580D-1 is a single-ended active clamp/reset PWM controller manufactured by Texas Instruments. It operates within an extended temperature range of 0°C to +70°C and utilizes a SOIC (D) package with 16 pins. The device supports Boost, Buck, Flyback, and Forward topologies. Key electrical parameters include a switching frequency of 430 kHz, a maximum duty cycle of 69%, and an output current capability of 1.2 A. The output voltage is rated at 15 V. Transition times are specified as 20 ns for fall time and 40 ns for rise time.

DC DC Switching Controllers Feature Summary

• Integrates P-channel clamp FET for active clamp applications
• Provides 16V turn-on gate drive capability
• Supports multiple power converter topologies including Boost, Buck, Flyback, and Forward

DC DC Switching Controllers Applications

• Single-ended active clamp forward converters
• Active reset flyback converters
• Buck and Boost power supply designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix designation when ordering, as variants such as UCC3580DTR-1 exist with identical core functionality but different packaging formats. Confirm that the SOIC-D package aligns with your PCB footprint requirements. Ensure the operating temperature range of 0°C to +70°C meets your system's thermal environment specifications before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring integrated active clamp control without external FET drivers. The built-in P-channel clamp simplifies circuit topology compared to discrete solutions. Consider the 430 kHz switching frequency for balancing efficiency and component size. Verify compatibility with the supported topologies if designing non-forward or flyback architectures.

DC DC Switching Controllers Part Context

This part belongs to the UCC3580 series of single-ended active clamp/reset PWM controllers. It is functionally related to variants like UCC3580D-3 and UCC3580DTR-1, which share similar electrical characteristics but may differ in packaging or temperature ratings. The series targets efficient power conversion in isolated and non-isolated applications.

DC DC Switching Controllers Replacement Considerations

UCC3580D-3 serves as a potential alternative with similar electrical specifications. Verify package compatibility and temperature range differences between the D-1 and D-3 variants before substitution.
