Описание

The UCC28600-Q1 is a PWM controller with advanced energy features to meet stringent world-wide energy efficiency requirements. UCC28600-Q1 integrates built-in advanced energy saving features with high level protection features to provide cost effective solutions for energy efficient power supplies. UCC28600-Q1 incorporates frequency fold back and green mode operation to reduce the operation frequency at light load and no load operations. UCC28600-Q1 is offered in the 8-pin SOIC (D) package. Operating ambient temperature range is 40°C to 105°C. The Design Calculator, (Texas Instruments Literature number SLVC104), located in the Tools and Software section of the UCC28600-Q1 product folder, provides a user-interactive iterative process for selecting recommended component values for an optimal design.
