UC2838AQ

Overview

The UC2838AQ is a magnetic amplifier controller manufactured by Unitrode, classified under specialized ICs. It operates in surface-mount configurations within a 20-PLCC (9x9) package, also described as a 20-LCC (J-Lead) case. The device functions specifically as a controller for magnetic amplifier circuits, designed to manage secondary rectification in power supply systems. This component type supports efficient power regulation through precise control of magnetic amplifier elements.

Feature Summary

Integrated magnetic amplifier controller for power supply applications
Available in 20-pin PLCC/J-Lead surface-mount package
Designed for high-efficiency secondary side rectification control

Applications

High-frequency switching power supplies
Post-regulation stages in DC-DC converters
Power factor correction circuits requiring secondary control

Procurement Notes

Verify the manufacturer designation carefully, as Unitrode was acquired by Texas Instruments. Ensure the specific 'AQ' suffix meets your environmental or automotive qualification requirements if applicable, as standard versions may differ. Confirm the 20-PLCC footprint compatibility with your PCB design before ordering.

Selection Notes

Select this component when designing power supplies that utilize magnetic amplifiers for post-regulation. Ensure the operating frequency and current capabilities of the external magnetic components match the controller's drive specifications. Verify thermal management needs for the 20-PLCC package in enclosed environments.

Part Context

This part belongs to the UC2838 family of controllers, originally developed by Unitrode. These devices are widely used in multi-output power supplies where tight cross-regulation is required. The transition from Unitrode to Texas Instruments has maintained the functionality of these legacy parts in modern inventory.

Replacement Considerations

Check for direct equivalents such as the UCC2838 series from Texas Instruments, which maintains pin compatibility. Verify if the 'A' grade temperature range is sufficient or if the 'Q' automotive qualification is strictly necessary for the target application.
