UC2854ANG4

Overview

The UC2854ANG4 is an enhanced high-power factor preregulator manufactured by Texas Instruments. It operates within a supply voltage range of 10 V to 20 V and features a switching frequency of 200 kHz. The device draws a typical operating supply current of 250 µA. It is designed for through-hole installation in a 16-pin PDIP package. The component supports an extended industrial temperature range, functioning reliably from -40°C to +85°C.

Feature Summary

Enhanced high-power factor preregulation architecture
Average current mode control technique
Integrated zero power detection capability

Applications

Power factor correction (PFC) stages in AC-DC converters
High-power factor preregulators for power supplies
Industrial power management systems requiring PFC compliance

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliant with RoHS standards as per Texas Instruments documentation. Confirm that the PDIP-16 package matches the required through-hole mounting specifications for the target PCB design. Ensure the operating temperature range aligns with the environmental conditions of the final application.

Selection Notes

Select this component when an enhanced version of the UC2854 is required for improved performance in power factor correction applications. The through-hole PDIP-16 package is suitable for prototyping or designs mandating mechanical robustness over surface mount alternatives. Consider the 200 kHz switching frequency and 250 µA supply current when designing auxiliary power circuits and thermal management strategies.

Part Context

The UC2854ANG4 belongs to the UC2854A series of advanced high-power factor preregulators from Texas Instruments. It serves as a specialized power management IC within the PMIC category, specifically engineered for PFC applications. The 'G4' suffix typically denotes a lead-free variant within the manufacturer's product lineup.
