Frequently Asked Questions
What is the UCC28C44DGK and what does it do?
The UCC28C44DGK is a BiCMOS current-mode PWM controller from Texas Instruments in an MSOP-8 package. It provides current-mode control up to 500kHz switching frequency with 1A peak gate drive output, programmable soft-start, and undervoltage lockout (UVLO) protection. It is designed for isolated DC-DC converters and SMPS applications.
What package and pin count does the UCC28C44DGK have?
The UCC28C44DGK comes in an MSOP-8 (Mini Small Outline Package) with 8 pins. The DGK suffix specifically denotes the MSOP-8 package variant, making it suitable for space-constrained PCB designs compared to the larger SOIC-8 variants.
What is the operating temperature range of the UCC28C44DGK?
The UCC28C44DGK operates over an industrial temperature range of -40°C to +125°C, making it suitable for automotive, industrial, and outdoor applications where wide temperature tolerance is required.
What are common alternatives to the UCC28C44DGK?
Common alternatives to the UCC28C44DGK include the UC3844BD (STMicroelectronics), NCP1200 (onsemi), and UCC28C43DGK (TI lower frequency variant). These are compatible current-mode PWM controllers with similar topologies and can be used as drop-in or near drop-in replacements in flyback/forward converter designs.
What is the minimum order quantity and pricing for UCC28C44DGK?
The UCC28C44DGK is available with a minimum order quantity (MOQ) of 400 pieces. Pricing starts at approximately $1.46 per unit for 400-piece orders and drops to $1.05 per unit at 10,000 pieces. Contact us for a quote on custom quantities and lead times.
