LD7550 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 compensation and the small SOT-26 package provide the users a high efficiency, low external component 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 applications. The LD7550 is with both SOT-26 and DIP-8 package.
