Texas Instruments' TPS92510 is optimized for DC/DC step-down (buck) LED illumination applications such as retrofit LED based MR-16 replacement; multiple LED string lighting such as high-bay and street lights; and other high light-output applications such as emergency and flash lighting. At the time of release, the TPS92510 is the first DC/DC buck with integrated FET in the market which can deliver 1.5 A at up to 97% efficiency with user configurable switching frequency, PWM LED current modulation and thermal foldback - three key common customer requests in DC LED lighting. Previous solutions require additional external components to achieve similar performance while adding size and cost to the lighting solution.
