Frequently Asked Questions
What is the UCC28C45DRG4 used for?
The UCC28C45DRG4 is a current-mode PWM controller designed for switched-mode power supplies including flyback, forward, and boost converters. It provides precise regulation via current-mode control with slope compensation, making it suitable for industrial power supplies, telecom DC-DC converters, and solar inverter stages.
What package and pin count does the UCC28C45DRG4 come in?
The UCC28C45DRG4 comes in an 8-pin SOIC package (D suffix). The R suffix denotes tape-and-reel packaging (typically 2500 units per reel), and the G4 suffix confirms RoHS-compliant, Pb-free construction.
What is the operating temperature range of the UCC28C45DRG4?
The UCC28C45DRG4 operates over a temperature range of -40°C to 105°C, making it suitable for industrial and extended commercial applications where ambient temperatures may vary significantly.
What are common alternatives to the UCC28C45DRG4?
Compatible alternatives include the UC3845BD (STMicroelectronics, SOIC-8, same current-mode PWM architecture), NCP1200AD100R2G (ON Semiconductor, SOIC-8, PWM controller), and UCC28C44DRG4 (TI, SOIC-8, lower max frequency variant). All share the standard UC384x pinout.
Is the UCC28C45DRG4 RoHS compliant?
Yes. The G4 suffix confirms the UCC28C45DRG4 is RoHS compliant and lead-free (Pb-free), meeting EU RoHS Directive 2011/65/EU requirements and suitable for designs targeting European and other regulated markets.
