Product Introduction
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, 0.7-A 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 V_IN. 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 V_OUT. This current limiting scheme reduces load current foldback. Additional protection features include: Thermal Shutdown, V_CC undervoltage lockout, gate drive undervoltage lockout, and Max Duty Cycle limiter.
