UC3854ADW

Overview

The UC3854ADW is a high power-factor preregulator integrated circuit manufactured by Texas Instruments. It operates within an industrial temperature range of 0°C to +70°C and utilizes a 16-SOIC surface-mount package. The device supports a switching frequency of 200 kHz and features a low operating supply current of 1.5 mA. Designed for power factor correction applications, it integrates essential control functions into a compact form factor suitable for efficient power management systems.

Feature Summary

Integrated high power-factor preregulator controller
Current-mode control architecture
Low operating supply current consumption

Applications

Power factor correction circuits
High power-factor preregulators
Switched-mode power supplies

Procurement Notes

Verify the specific suffix 'A' indicates the extended commercial/industrial temperature grade (0°C to +70°C) compared to standard variants. Confirm the 'DW' suffix corresponds to the SOIC-16 package type. Ensure compatibility with moisture sensitivity levels if storage conditions are critical. Cross-reference the manufacturer part number directly with official Texas Instruments documentation to avoid confusion with similar UC3854 series components.

Selection Notes

Select this component when designing power factor correction stages requiring a dedicated controller with integrated current-mode control. The ADW variant is appropriate for applications needing operation up to 70°C ambient temperature. Consider the 200 kHz switching frequency for magnetic component sizing. Verify that the SOIC-16 footprint fits the PCB layout constraints and thermal requirements of the target design.

Part Context

The UC3854 belongs to a family of power factor correction controllers from Texas Instruments. The UC3854ADW specifically denotes the industrial temperature grade version in a surface-mount package. This component is part of the broader PMIC category, focusing on improving input power quality in AC-DC conversion systems through active PFC techniques.

Replacement Considerations

UC3854BDW is a documented alternative within the same product family offering identical functionality but potentially different temperature or packaging specifications.
