Unregulated IC Supply Voltage Input – Input range from +1.6V to 6.0V. Bypass with a 1
μ
for operation below 2.0V.
Feedback Input – Connects to a current sense resistor between the output load and GND to set the output
current.
Active-Low Shutdown Input – A logic low shuts down the device and reduces the supply current to 0.2
μ
A (Typ).
Connect
SHDN
to V
CC
for normal operation.
MOSFET Gate Driver – Connects to an external N-Channel MOSFET.
Current-Sense Amplifier Input – Connecting a resistor between CS and GND sets the peak inductor current limit.
Common terminal for ground reference.
Adjustment Signal Input – Provides the internal reference, via an internal filter and gain resistor, allowing a
dynamic output current adjustment corresponding to a varying duty cycle. The actual ADJ pin voltage range is
from V
IN
to GND. In order to minimize the current sense resistor power dissipation a practical range of V
ADJ
=
0.0V to 0.5V should be used.
MOSFET Current Sense Input - Connects to the External N-Channel MOSFET Source.
