LM5007SNVS252G –SEPTEMBER 2003–REVISED NOVEMBER 2015
LM5007 High Voltage 80-V Step Down Switching Regulator Features 3 DescriptionThe LM5007 Step Down Switching Regulator features Integrated 80-V, 0.7-A N-Channel Buck Switch allof the functions neededto implement low cost,• Internal HV VCC Regulator efficient, Buck bias regulators. This high voltage• No Control Loop Compensation Required regulator contains an 80-V, 0.7-A N-Channel Buck
Switch. The deviceis easyto apply andis providedin• Ultra-Fast Transient Response the VSSOP-8 and the thermally enhanced WSON-8• On Time Varies Inversely with Line Voltage packages. The regulatoris based ona hysteretic• Operating Frequency Nearly Constant with control scheme using an on time inverselyVarying Line Voltage proportionalto VIN. This feature allows the operating
frequencyto remain relatively constant with load and• Adjustable Output Voltage
input voltage variations. The hysteretic control• Highly Efficient Operation requires no control loop compensation, while• Precision Reference providing very fast load transient response. An Low Bias Current intelligent current limitis implementedin the LM5007
with forced off time thatis inversely proportionalto• Intelligent Current Limit Protection VOUT. This current limiting scheme reduces load• Thermal Shutdown current foldback. Additional protection features• External Shutdown Control include: Thermal Shutdown, VCC undervoltage
lockout, gate drive undervoltage lockout, and Max• VSSOP-8 and WSON-8 Packages Duty Cycle limiter.
