UCC38C44DGKR

DC DC Switching Controllers Overview

The UCC38C44DGKR is a BiCMOS low-power current-mode PWM controller manufactured by Texas Instruments. It operates with a switching frequency of 1 MHz and supports Boost, Buck, Flyback, and Forward topologies. The device features a maximum duty cycle of 50%, an output voltage rating of 18 V, and an output current capability of 1 A. It functions within a temperature range of 0°C to +70°C and is housed in an 8-pin VSSOP package.

DC DC Switching Controllers Feature Summary

• Implements current-mode control architecture for efficient power management
• Designed for low-power applications using BiCMOS technology
• Supports multiple converter topologies including boost, buck, flyback, and forward

DC DC Switching Controllers Applications

• Boost converter designs
• Buck converter implementations
• Flyback power supply circuits
• Forward converter systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DGKR' indicates the reel packaging variant distinct from tube-packaged equivalents like DGK. Confirm the commercial grade temperature range (0°C to +70°C) aligns with system requirements, as industrial variants may carry different suffixes. Ensure compatibility with existing PCB footprints for the VSSOP-8 package during component sourcing.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a 1 MHz switching frequency and current-mode control. It is suitable for designs needing up to 1 A output current and supporting various isolated or non-isolated topologies. Consider the VSSOP-8 package size for space-constrained layouts and verify that the commercial temperature range meets operational environmental standards.

DC DC Switching Controllers Part Context

This part belongs to the UCC38C44 series of BiCMOS low-power current-mode PWM controllers. It shares functional similarities with other members of the family, such as the UCC28C44, though operating temperature ranges and packaging options may vary across specific suffixes within the broader product line.

DC DC Switching Controllers Replacement Considerations

UCC28C44DGKR serves as a verified alternative within the same family, offering similar functionality but potentially differing in temperature range or packaging configuration.
