LM5008  
High Voltage (100V) Step Down Switching Regulator  
General Description  
Features  
n Integrated 100V, N-Channel buck switch  
n Internal VCC regulator  
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  
compensation. An intelligent current limit is implemented  
with forced OFF time, which is inversely proportional to Vout.  
This scheme ensures short circuit protection while providing  
minimum foldback. Other protection features include: Ther-  
mal Shutdown, VCC under-voltage lockout, Gate drive under-  
voltage lockout, and Max Duty Cycle limiter  
n No loop compensation required  
n Ultra-Fast transient response  
n On time varies inversely with line voltage  
n Operating frequency remains constant with varying line  
voltage and load current  
n Adjustable output voltage  
n Highly efficient operation  
n Precision internal reference  
n Low bias current  
n Intelligent current limit protection  
n Thermal shutdown  
Typical Applications  
n Non-Isolated Telecommunication Buck Regulator  
n Secondary High Voltage Post Regulator  
n +42V Automotive Systems
