High Voltage (100V) Step Down Switching Regulator
General Description
The LM5008EP Step Down Switching Regulator features all
of the functions needed to implement a low cost, efficient,
Buck bias regulator. This high voltage regulator contains an
100 V N-Channel Buck Switch. The device is easy to imple-
ment and is provided in the MSOP-8 and the thermally en-
hanced LLP-8 packages. The regulator is based on a
hysteretic control scheme using an ON time inversely pro-
portional to V
IN. This feature allows the operating frequency
to remain relatively constant. The hysteretic control requires
no loop compensation. An intelligent current limit is imple-
mented with forced OFF time, which is inversely proportional
to Vout. This scheme ensures short circuit protection while
providing minimum foldback. Other protection features in-
clude: Thermal Shutdown, V
CC under-voltage lockout, Gate
drive under-voltage lockout, and Max Duty Cycle limiter
