LD7550 Datasheet | Unknown Manufacturer

8/27/2004 Green-Mode PWM Controller General Description The LD7550 is a low cost, low startup current, current mode PWM controller with green-mode power-saving operation. The integrated functions such as the leading-edge blanking of the current sensing, internal slope pensation and the small SOT-26 package provide the users a high efficiency, low external ponent counts, and low cost solution for AC/DC power applications. The special green-mode control is not only to achieve the low power consumption but also to offer a non-audible-noise operation when the LD7550 is operating under light load or no load condition. The LD7550 is designed for the low power adaptor or charger...
