High Voltage (80V) Step Down Switching Regulator
General DescriptionThe LM5007 Step Down Switching Regulator featuresallof
the functions neededto implement low cost, efficient, Buck
bias regulators. This high voltage regulator containsan80V,
0.7A N-Channel Buck Switch. The deviceis easyto apply
andis providedinthe MSOP-8 and the thermally enhanced
LLP-8 packages. The regulatoris basedona hysteretic
control scheme usinganon time inversely proportionalto
VIN. This feature allows the operating frequencyto remain
relatively constant with load and input voltage variations. The
hysteretic control requiresno control loop compensation,
while providing very fast load transient response.An intelli-
gent current limitis implementedinthe LM5007 with forced
off time thatis inversely proportionalto 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.
