UC3834DW

Overview

The UC3834DW is a high-efficiency linear regulator controller manufactured by Unitrode Corporation. It is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, specifically identified as SOP-16 or PDSO16. The device functions as a switching controller designed for power management applications, utilizing BICMOS technology. It supports a nominal input voltage of 12 V, with an operating range extending from a minimum of 10.3 V to a maximum of 15 V. The component is rated for surface mount installation and operates within a standard commercial temperature range up to 70 °C.

Feature Summary

• High-efficiency linear regulation architecture
• Current-mode control implementation
• Integrated pulse width modulation circuitry
• Surface-mount compatible packaging

Applications

• General power supply management systems
• Linear regulator controller circuits
• DC-to-DC conversion modules

Procurement Notes

Verify the manufacturer origin carefully, as Texas Instruments acquired Unitrode's assets. Confirm the specific suffix 'DW' corresponds to the SOIC-16 package variant. Ensure compliance requirements are checked against the 'Not Qualified' status found in some databases. Validate that the component matches the BICMOS process technology described in official documentation before integration into designs.

Selection Notes

Select this component when a current-mode controlled linear regulator solution is required. The 16-pin SOIC form factor suits automated surface-mount assembly processes. Consider the 15 V maximum input limit and 70 °C thermal ceiling during system design. Verify availability through authorized distributors given the historical manufacturer transition from Unitrode to Texas Instruments.

Part Context

This part belongs to the UC383x family of power management integrated circuits originally developed by Unitrode Corporation. These devices are engineered for efficient voltage regulation tasks. The DW suffix denotes the plastic small outline package configuration. The family provides robust control features for stabilizing output voltages in various electronic power systems.
