LM5007EP
Enhanced Plastic High Voltage (80V) Step Down
Switching Regulator
General Description
The LM5007EP 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 propor-
tional to V
IN. This feature allows the operating frequency to
remain relatively constant with load and input voltage varia-
tions. The hysteretic control requires no control loop com-
pensation, while providing very fast load transient response.
An intelligent current limit is implemented in the LM5007EP
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,
Vcc undervoltage lockout, gate drive undervoltage lockout,
and Max Duty Cycle limiter.
