UCC28019DRG4

Overview

The UCC28019DRG4 is a continuous conduction mode (CCM) power factor correction controller manufactured by Texas Instruments. It operates within an extended temperature range of -40°C to +125°C and utilizes an SOIC-8 surface-mount package. The device functions at a switching frequency of 65 kHz with a typical operating supply current of 100 µA. This component is part of the UCC28019 series, designed for high-efficiency power factor correction applications.

Feature Summary

• Implements continuous conduction mode control for power factor correction
• Features low quiescent current consumption for improved efficiency
• Designed for operation across wide industrial temperature ranges

Applications

• Power factor correction in AC-DC power supplies
• Industrial power management systems
• Consumer electronics power adapters

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the 65 kHz switching frequency aligns with your electromagnetic interference constraints and transformer design specifications before finalizing procurement.

Selection Notes

Select this component when continuous conduction mode operation is required for higher power levels compared to boundary mode controllers. The low operating supply current makes it suitable for applications where standby power consumption is critical. The wide operating temperature range supports deployment in harsh industrial environments without derating concerns.

Part Context

This device belongs to the UCC28019 family of power factor correction controllers from Texas Instruments. The family focuses on CCM PFC solutions, distinguishing itself from discontinuous or transition mode alternatives. The DRG4 designation indicates a specific tape-and-reel packaging variant with lead-free construction, adhering to environmental standards.

Replacement Considerations

The UCC28019DR serves as the standard non-green version of this component. Verify if the lead-free requirement is mandatory for your assembly process. No other direct functional substitutes are explicitly documented in the provided source material.
