OPERATION OF STEP-UP DC/DC CONVERTER  
Step-up DC/DC Converter charges energy in the inductor when Lx Transistor (LxTr) is ON, and discharges the  
energy with the addition of the energy from Input Power Source thereto when LxTr is off, so that a higher output  
voltage than the input voltage is obtained.  
The operation will be explained with reference to the following diagrams:

T=1/ fosc  
Step.1 : LxTr is turned on and current IL (= i1 ) flows, so that energy is charged in L. At this moment, IL(=i1 ) is  
increased from ILmin (= 0) to reach ILmax in proportion to the on-time period (ton) of LxTr.  
Step.2 : When LxTr is turned off, Schottky diode (SD) is turned on in order that L maintains IL at ILmax, so that  
current IL (= i2) is released.  
Step.3 : IL (=i2) is gradually decreased, and in the case of discontinuous mode, IL reaches ILmin (=0) after a time  
period of topen, so that SD is turned off.  
In the case of the VFM control system, with the on-time period (ton) maintained constant, the output voltage  
is maintained constant by controlling the oscillator frequency (fosc).
