Green-Mode PWM Controller with High-Voltage  
Start-Up Circuit  
REV: 04a  
General Description  
Features  
The LD7575 is a current-mode PWM controller with  
excellent power-saving operation. It features a high-  
voltage current source to directly supply the startup current  
from bulk capacitor and further to provide a lossless startup  
circuit. 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.
