High Voltage (80V) Step Down Switching Regulator  
General Description  
Features  
n Integrated 80V, 0.7A N-Channel Buck Switch  
n Internal HV Vcc Regulator  
The LM5007 Step Down Switching Regulator features all of  
the functions needed to implement low cost, efficient, Buck  
bias regulators. This high voltage regulator contains an 80 V,  
0.7A N-Channel Buck Switch. The device is easy to apply  
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 with load and input voltage variations. The  
hysteretic control requires no control loop compensation,  
while providing very fast load transient response. An intelli-  
gent current limit is implemented in the LM5007 with forced  
off time that is inversely proportional to VOUT. This current  
limiting scheme reduces load current foldback. Additional  
protection features include: Thermal Shutdown, Vcc under-  
voltage lockout, gate drive undervoltage lockout, and Max  
Duty Cycle limiter.
