Product Description
The LD7552B ( including LD7552B PS , LD7552B GS , LD7552B PN ) are 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 package provide the users a high efficiency, minimum external component counts, and low cost solution for AC/DC power applications.The special green-mode control does not only achieve low power consumption but also offer a non-audible-noise operation when the LD7552B operates under light load or no load condition.The LD7552B is designed for the switching adaptor with 30W~60W output.
