UC3854DWTRG4

Overview

The UC3854DWTRG4 is an enhanced high power factor preregulator controller manufactured by Texas Instruments. It operates in a current-mode control architecture with pulse width modulation, designed for power factor correction applications. The device features a fixed switching frequency of 200 kHz and supports an operating supply voltage range of 14.5 V to 30 V. It functions within a commercial temperature range of 0°C to +70°C. The component is housed in a 16-pin SOIC package and utilizes surface-mount installation. It includes a startup current specification of 1.5 mA and complies with RoHS standards.

Feature Summary

Implements average current mode control for precise power factor correction
Integrates a fixed 200 kHz oscillator for consistent switching performance
Features built-in protection mechanisms including undervoltage lockout

Applications

High power factor preregulators
Power factor correction circuits
AC-DC power supplies

Procurement Notes

Verify the presence of the 'G4' suffix to confirm lead-free compliance and specific manufacturing lot details. Ensure the SOIC-16 package matches the PCB footprint requirements. Confirm that the 200 kHz switching frequency aligns with the electromagnetic interference constraints of the target design. Validate the commercial temperature rating against the operational environment specifications.

Selection Notes

Select this component when a dedicated PFC controller with current-mode operation is required. The UC3854 series is suitable for designs needing high efficiency and low harmonic distortion. Consider the 16-pin SOIC package size for space-constrained layouts. Evaluate the 200 kHz frequency against filter component sizing needs. Compare against other UC3854 variants if different packaging or temperature ratings are necessary.

Part Context

This part belongs to the UC3854 family of power factor correction controllers from Texas Instruments. The family includes variants such as UC3854AN, UC3854BDW, and UC3854ADWTR. These devices share similar functional architectures but differ in packaging, temperature ranges, and specific electrical characteristics. The UC3854DWTRG4 represents the tape-and-reel version of the enhanced DW variant with lead-free compliance.
