UC3879DWTR

DC DC Switching Controllers Overview

The UC3879DWTR is a phase-shift resonant controller from Texas Instruments, designed for half-bridge and full-bridge DC-DC converter topologies. It operates within a supply voltage range of 9V to 20V and supports switching frequencies up to 300 kHz. The device features four output channels with a maximum output current of 100 mA per channel. It is housed in a 20-SOIC package and functions within an operating temperature range of 0°C to 70°C.

DC DC Switching Controllers Feature Summary

• Supports phase-shift control for resonant converters
• Includes programmable output turn-on delay
• Compatible with voltage mode or current mode topologies

DC DC Switching Controllers Applications

• Half-bridge DC-DC converters
• Full-bridge DC-DC converters
• Resonant power supply designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (DWTR) indicates the SOIC-20 surface-mount package and tape-and-reel packaging configuration. Confirm that the component meets RoHS 3 compliance standards as specified in the datasheet. Ensure the ordering part number matches the required temperature grade and pinout configuration for the target application design.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring phase-shifted full-bridge or half-bridge architectures. It is suitable for designs needing integrated soft-start and frequency control capabilities. Consider the 20-SOIC package constraints and thermal requirements when designing the PCB layout for optimal performance.

DC DC Switching Controllers Part Context

This component belongs to the UC series of PWM controllers by Texas Instruments. It is specifically engineered for high-efficiency resonant switching applications. The device integrates essential control features such as ramp compensation and soft-start to stabilize power conversion systems.

DC DC Switching Controllers Replacement Considerations

The UC3879DW is the non-tape-and-reel variant of the same controller in a SOIC-20 package. Verify if the reel packaging requirement can be relaxed to use the standard tube-packaged version.
