DESCRIPTION  
On Time Varies Inversely With Input Voltage  
The SM72485 Step Down Switching Regulator  
features all of the functions needed to implement a  
low cost, efficient, Buck bias regulator. This high  
voltage regulator contains an 100 V N-Channel Buck  
Switch. The device is easy to implement and is  
provided in the VSSOP and the thermally enhanced  
WSON package. The regulator is based on a control  
scheme using an ON time inversely proportional to  
VIN. This feature allows the operating frequency to  
remain relatively constant. The control scheme  
requires no loop compensation. An intelligent current  
limit is implemented with forced OFF time, which is  
inversely proportional to Vout. This scheme ensures  
short circuit control while providing minimum  
foldback. Other features include: Thermal Shutdown,  
VCC under-voltage lockout, Gate drive under-voltage  
lockout, Max Duty Cycle limiter, and a pre-charge  
switch.
