Frequently Asked Questions
What is the UCC28C45DGKR and what does it do?
The UCC28C45DGKR is a current-mode PWM controller IC from Texas Instruments designed for switch-mode power supply applications. It features internal leading-edge blanking, a programmable oscillator up to 1 MHz, a wide 8.5V to 17V supply range, and 1A peak gate drive current. It is commonly used in flyback and forward converter topologies.
What package and pin count does the UCC28C45DGKR use?
The UCC28C45DGKR comes in an MSOP-8 (Mini Small Outline Package) with 8 pins. The MSOP-8 package offers a compact footprint suitable for space-constrained designs.
What is the operating temperature range of the UCC28C45DGKR?
The UCC28C45DGKR operates over an industrial temperature range of -40C to 105C, making it suitable for automotive-adjacent and harsh industrial environments.
What are common alternatives to the UCC28C45DGKR?
Functionally compatible alternatives include the UCC28C44DGKR (lower frequency variant), UC3845 (DIP/SOIC), and NCP1200 from ON Semiconductor for similar current-mode PWM control applications.
Is the UCC28C45DGKR RoHS compliant and what is its MSL rating?
Yes, the UCC28C45DGKR is fully RoHS compliant and lead-free. Its Moisture Sensitivity Level (MSL) is MSL1, meaning no special moisture precautions are required before soldering.
