DC DC Switching Controllers datasheet and documents for UCC38C45DGKR

UCC38C45DGKR

DC DC Switching Controllers Overview

The UCC38C45DGKR is a low-power current-mode switch controller manufactured by Texas Instruments. It operates with a fixed switching frequency of 1 MHz and supports boost, buck, flyback, and forward topologies. The device features a maximum duty cycle of 50% and provides a single output channel capable of driving external switches. It functions within a supply voltage range up to 18 V and delivers an output drive current of 1 A. The component is housed in an 8-pin VSSOP package and is rated for operation between 0°C and +70°C.

DC DC Switching Controllers Feature Summary

Current-mode control architecture for improved transient response
Fixed 1 MHz switching frequency enabling compact passive design
Versatile topology support including boost, buck, flyback, and forward configurations

DC DC Switching Controllers Applications

AC-DC power supplies
DC-DC converters
Battery chargers

DC DC Switching Controllers Procurement Notes

Verify the specific suffix DGKR against official datasheets to confirm the VSSOP-8 package and tape-and-reel delivery format. Ensure compatibility with the required operating temperature range of 0°C to +70°C. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 1 MHz frequency and 50% maximum duty cycle are required for non-isolated or isolated converter designs. It is suitable for applications needing low quiescent current and high efficiency. Compare against the UCC38C40 series if a higher duty cycle capability is necessary for the specific topology.

DC DC Switching Controllers Part Context

This part belongs to the UCCx8C4x family of low-power current-mode controllers from Texas Instruments. These devices are designed for cost-sensitive and space-constrained power management solutions. The UCC38C45 variant specifically limits the duty cycle to 50%, distinguishing it from other members of the family that may offer wider duty cycle ranges.
