UCC38500DW

Overview

The UCC38500DW is a BiCMOS Power Factor Correction (PFC) and PWM combination controller manufactured by Texas Instruments, housed in a 20-pin SOIC package. It integrates average current mode PFC control with a post-regulator PWM controller for high-efficiency power supplies. The device operates within a temperature range of 0 to 70 degrees Celsius and supports switching frequencies up to 120 kHz.

Feature Summary

Integrates average current mode PFC controller with a post-regulator PWM controller
Supports synchronous operation between the PFC stage and the downstream converter
Provides comprehensive protection features including overvoltage and undervoltage lockout

Applications

High-efficiency power factor correction pre-regulators
Universal input AC-DC power supplies
Computer and peripheral power systems

Procurement Notes

Verify the manufacturer designation on the datasheet, as Unitrode was acquired by Texas Instruments. Confirm the specific suffix indicates the standard tube packaging variant. Ensure the component meets the required thermal and electrical specifications for the target application environment before procurement.

Selection Notes

Select this component for designs requiring integrated PFC and PWM control in a single package. It is suitable for applications needing average current mode control to achieve high power factors. Consider the 20-pin SOIC package constraints and the operational temperature range when designing the thermal management system.

Part Context

This part belongs to the UCC385xx series of power management ICs. It represents the evolution of Unitrode's legacy PFC controllers under Texas Instruments. The device combines functionalities previously handled by separate chips, simplifying the design of complex power supply architectures.

Replacement Considerations

Direct substitutes include the UC3854BDW for basic PFC functions, though it lacks the integrated PWM controller. For full integration, consider the UCC38502DW or UCC38503DW variants which offer similar combined control capabilities.
