UCC2804DTRG4

Overview

The UCC2804DTRG4 is a current-mode PWM controller manufactured by Texas Instruments, designed for high-performance power supplies. It supports Boost, Flyback, and Forward topologies with a maximum switching frequency of 1 MHz. The device operates within a supply voltage range of 8.3V to 12V and features a maximum duty cycle of 50%. Packaged in an 8-SOIC surface-mount format, it ensures reliable operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Implements current-mode control architecture for enhanced transient response and simplified compensation.

Applications

• Boost converter designs
• Flyback transformer-isolated power supplies
• Forward converter applications

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm compliance with RoHS-3 standards and lead-free manufacturing processes. Ensure that the ordering information matches the exact package type and tape-and-reel specifications required for automated assembly lines.

Selection Notes

Select this component when designing isolated or non-isolated converters requiring current-mode regulation. It is suitable for applications needing a 50% duty cycle limit and support for multiple standard power topologies. Confirm that the input voltage range aligns with the 8.3V to 12V operating window.
