2 Proposed LED Drive Designs With Analog Dimming

Section 2.1 through Section 2.3 shows three scenarios that TI currently proposes for driving an LED with the analog dimming function. Each design has benefits and drawbacks. Designer can select the best design from proposals to meet specific application according performance, cost, and package .
