Pin Function Description
1LX
Inductor input. Inductor L connected between this pin and the battery
2VIN
Input Voltage. Connect directly to battery
3
LBI/SD
Low battery detect input and shutdown. Low battery detect threshold
is set with this pin using a potential divider. If this pin is pulled to logic low
then the device will shutdown.
4
SEL
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.
5
POK
(ILC6363CIR-XX
Power Good Output. This open drain output pin will go high when
output voltage is within regulation, 0.92•VOUT(NOM) < Vthreshold <
0.98•VOUT(NOM)
VFB
(ILC6363CIR-ADJ)
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.
6
LBO
Low Battery Output. This open drain output will go low if the battery
voltage is below the low battery threshold set at pin 3.
7
GND
Ground of the IC. Connect this pin to the battery and system ground
8VOUT
Regulated output voltage.
