LM5008  
High Voltage (100V) Step Down Switching Regulator  
General Description  
Features  
The LM5008 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 MSOP-8 and the thermally enhanced LLP-8  
packages. The regulator is based on a hysteretic control  
scheme using an ON time inversely proportional to VIN. This  
feature allows the operating frequency to remain relatively  
constant. The hysteretic control requires no loop compensa-  
tion. An intelligent current limit is implemented with forced  
OFF time, which is inversely proportional to Vout. This  
scheme ensures short circuit protection while providing min-  
imum foldback. Other protection features include: Thermal  
Shutdown, VCC under-voltage lockout, Gate drive under-volt-  
age lockout, and Max Duty Cycle limiter  
Integrated 100V, N-Channel buck switch  
Internal VCC regulator  
No loop compensation required  
Ultra-Fast transient response  
On time varies inversely with line voltage  
Operating frequency remains constant with varying line  
voltage and load current  
Adjustable output voltage  
Highly efficient operation  
Precision internal reference  
Low bias current  
Intelligent current limit protection  
Thermal shutdown
