image of Texas Instruments' UCC28600 PWM Controller Texas Instruments' UCC28600 is a PWM controller with advanced energy features to meet stringent world-wide energy efficiency requirements. UCC28600 integrates built-in advanced energy saving features with high level protection features to provide cost effective solutions for energy efficient power supplies. UCC28600 incorporates frequency fold back and green mode operation to reduce the operation frequency at light load and no load operations.

UCC28600 is offered in the 8-pin SOIC (D) package. Operating junction 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 product folder, provides a user-interactive iterative process for selecting recommended component values for an optimal design.
