UC2842ADWTRG4

Power Supply Controllers, Monitors Overview

The UC2842ADWTRG4 is a current-mode PWM controller manufactured by Texas Instruments, housed in a 16-pin SOIC package. It operates within an input voltage range of 11 V to 25 V, with a nominal supply of 15 V. The device supports pulse width modulation control techniques and functions as a switching controller. It is designed for industrial temperature ranges, operating reliably between -40°C and +85°C. The component complies with RoHS standards and is lead-free.

Power Supply Controllers, Monitors Feature Summary

• Implements current-mode pulse width modulation control architecture
• Provides robust operation across extended industrial temperature environments
• Features a 16-pin surface-mount SOIC package design

Power Supply Controllers, Monitors Applications

• Industrial power supply systems
• DC-to-DC converter topologies
• Battery charger circuits

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'RG4' confirms lead-free and RoHS compliance status against the manufacturer's latest documentation. Ensure the 'DW' designation matches the required 16-SOIC package dimensions and thermal characteristics for your PCB layout. Confirm the device meets automotive or industrial qualification requirements if applicable to your system design.

Power Supply Controllers, Monitors Selection Notes

Select this component when a current-mode PWM controller is required for applications demanding operation up to 25 V input. The 16-pin SOIC form factor suits designs needing expanded pin access for auxiliary functions compared to standard 8-pin variants. Consider the -40°C to +85°C rating for environments exceeding commercial temperature limits.

Power Supply Controllers, Monitors Part Context

This part belongs to the UC2842 family of current-mode PWM controllers from Texas Instruments. It shares functional similarities with other members like the UC2842N but differs in packaging and environmental ratings. The 'A' prefix typically denotes enhanced performance specifications, while 'DWTRG4' specifies the tape-and-reel delivery in a 16-SOIC package.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include UC2842DW and UC2842D. Verify pin compatibility and electrical parameters before substitution.
