Description :

LD7660J 5/21/2009 Low Power Off-line Switcher P03 (Internal use only) General Description The LD7660J integrated a 600V power MOSFET and a current mode PWM controller in a DIP-8 package. It’s operating at fixed frequency of 65 kHz. It provides important functions needed for a low output power applications such as leading-edge blanking of the current sensing, internal slope compensation, and green-mode power-saving operation under light load or no load condition. This highly integrated device provides the users a high efficiency, low external component counts, and low cost solution for low power adaptor or charger 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 LD7660J is operating under light load or no load condition.
