High Voltage (80V) Step Down Switching Regulator

FEATURES  
DESCRIPTION  
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 VSSOP-8 and the thermally enhanced WSON-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  
intelligent 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 undervoltage  
lockout, gate drive undervoltage lockout, and Max  
Duty Cycle limiter.
