The LM5008 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 implement
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 proportional 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 implemented
with forced OFF time, which is inversely proportional to Vout.
This scheme ensures short circuit protection while providing
minimum foldback. Other protection features include: Ther-

If an auxiliary voltage is available to raise the

(7V), the internal series pass regulator will

shutdown, reducing the IC power dissipation. Do not

exceed 14V. This voltage provides gate drive power

for the internal Buck switch. An internal diode is

provided between this pin and the BST pin. A local
