Design for High Efficient Power Supply at both Full Load and Light Load  
In case of leading edge modulation, the switch is turned  
OFF right at the leading edge of the system clock. When the  
modulating ramp reaches the level of the error amplifier output  
voltage, the switch will be turned ON. The effective duty-cyle  
of the leading edge modulation is determined during OFF tme  
of the switch.  
Figure 5 shows a leading edge control sche
One of the advantages of this control tehnique is thait  
required only one system clock. Switch 1(SW1) turns nd  
switch 2 (SW2) turns on at the same instat to minihe  
momentary “no-load” period, thus lowerig ripple volge  
generated by the switching action. With sh ynhroned  
switching, the ripple voltage of the first gis reducd.  
Calculation and evaluation have showthathe 120Hz
