UC2838AN

Overview

The UC2838AN is a magnetic amplifier controller manufactured by Unitrode, designed for applications requiring precise control of magnetic amplifiers. Housed in a 16-pin Dual In-line Package (DIP) with a 0.300-inch (7.62mm) width, this component supports through-hole mounting. It belongs to the specialized integrated circuits category, specifically functioning as a dedicated controller for magnetic amplifier systems. The device is supplied in bulk packaging and is intended for industrial or commercial power conversion designs where magnetic amp regulation is required.

Feature Summary

• Integrated magnetic amplifier controller functionality
• 16-pin DIP package (0.300 inch / 7.62mm width)
• Through-hole mounting capability
• Bulk packaging format

Applications

• Magnetic amplifier power supply systems
• Industrial power regulation circuits
• Specialized DC-DC conversion topologies utilizing magnetic amps

Procurement Notes

Verify the 16-DIP physical dimensions and through-hole compatibility during integration. Confirm that the bulk packaging format aligns with assembly line requirements. Ensure the application design strictly utilizes magnetic amplifier control principles compatible with this specific Unitrode controller architecture.

Selection Notes

Select the UC2838AN when a dedicated magnetic amplifier controller is required rather than a general PWM IC. The 16-pin DIP form factor is suitable for prototyping or legacy board designs. Compare against other Unitrode magnetic amp controllers if higher integration or surface-mount options are needed for production volumes.

Part Context

This component falls under Unitrode's specialized IC lineup, distinct from their standard PWM controllers like the UC384x series. While similar in vintage and manufacturer lineage, the UC2838AN is purpose-built for magnetic amplifier feedback loops, offering a different architectural approach compared to standard current-mode PWM controllers used in flyback or forward converters.

Replacement Considerations

Direct pin-to-pin replacements for magnetic amplifier controllers are rare due to niche functionality. Evaluate generic PWM controllers only if the circuit design can be modified to replace the magnetic amplifier stage entirely. Consult Unitrode (now Texas Instruments) documentation for updated equivalents within the modern TI portfolio.
