ESCRIPTION
IN
Unregulated IC Supply Voltage Input – Input range from +1.6V to 6.0V. Bypass with a 1
μ
F or greater capacitor
for operation below 2.0V.
Feedback Input – Connect to a resistive divider network between the output and GND to set the voltage at V
FB
(see Output Voltage Programming: Application Information).
Active-Low Shutdown Input – A logic low shuts down the device and reduces the supply current to 0.1
μ
A.
Connect
SHDN
to V
CC
for normal operation.
FB
SHDN
NDRV
MOSFET Gate Driver – Connects to an external N-Channel MOSFET.
CS
Current-Sense Amplifier Input – Connecting a resistor between CS and GND sets the peak inductor current limit.
GND
Common terminal for ground reference.
ADJ
An applied PWM Signal Input becomes the internal reference, via an internal filter and gain resistor, thus allowing
for a dynamic output voltage adjustment of
±
15% (i.e., corresponding to the duty cycle variance). Connecting this
pin to ground causes the device to revert to the internal voltage reference (note: refer to figure 8).
SRC
MOSFET Current Sense Input - Connects to the External N-Channel MOSFET Source.
