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.
