High Voltage (100V) Step Down Switching Regulator
High Voltage (100V) Step Down Switching Regulator
General Description
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
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-
mal Shutdown, V
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-
mal Shutdown, V

under-voltage lockout, Gate drive under-
voltage lockout, and Max Duty Cycle limiter

SW
Switching Node
Power switching node. Connect to the output
inductor, re-circulating diode, and bootstrap
capacitor.
2
BST
Boost Pin (Boot–strap capacitor input)
An external capacitor is required between the BST
and the SW pins. A 0.01µF ceramic capacitor is
recommended. An internal diode charges the
capacitor from V
CC
.

A resistor between this pin and RTN sets the
off-time when current limit is detected. The off-time
is preset to 35µs if FB = 0V.

This pin is connected to the inverting input of the
internal regulation comparator. The regulation
threshold is 2.5V.

IN
A resistor between this pin and V

sets the switch
on time as a function of V
IN
. The minimum
recommended on time is 400ns at the maximum
input voltage. This pin can be used for remote
shutdown.
7
V
CC
Output from the internal high voltage series pass
regulator. Regulated at 7.0V.
If an auxiliary voltage is available to raise the
voltage on this pin, above the regulation setpoint
(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
0.1µF decoupling capacitor is recommended. Series
pass regulator is current limited to 10mA.

Recommended operating range: 9.5V to 95V.
