Inductor input
Input Voltage
Low battery detect input and shutdown
set with this pin using a potential divider. If this pin is pulled to logic low
then the device will shutdown.
Select Input
. A low logic level signal applied to this pin selects PFM
operation mode. If the pin is left open or high logic level is applied, PWM
mode is selected.
Power Good Output
. This open drain output pin will go high when output
voltage is within regulation, 0.92*V
OUT(NOM)
Feedback Input
. This pin sets the adjustable output voltage via an
external resistor divider network. The formula for choosing the resistors is
shown in the “Applications Information” section.
This open drain output will go low if the battery voltage is below the low
battery threshold set at pin 3
Ground of the IC
. Connect this pin to the battery and system ground
