Pin Descriptions
VIN
Input supply voltage. Connect a 10μF ceramic capacitor to
power ground.
EN
Regulator enable pin. Enable the output when driven to high.
Shutdown the chip and discharge output capacitor when driven
to low. Do not leave this pin floating.
POR
200ms timer output. At power-up or EN HI, this output is a
200ms delayed Power-Good signal for the output voltage. This
output can be reset by a low RSI signal. 200ms starts when RSI
goes to high.
SKIP
Mode Selection pin. Connect to logic high or input voltage VIN
for PFM mode; connect to logic low or ground for forced PWM
mode. Do not leave this pin floating.
LX
Switching node connection. Connect to one terminal of
inductor.
GND
System ground.
VFB
Buck regulator output feedback. Connect to the output through
a resistor divider for adjustable output voltage (ISL8009-ADJ).
For preset output voltage, connect this pin to the output.
RSI
This input resets the 200ms timer. When the output voltage is
within the PGOOD window, an internal timer is started and
generates a POR signal 200ms later when RSI is low. A high
RSI resets POR and RSI high to low transition restarts the
internal counter if the output voltage is within the window,
otherwise the counter is reset by the output voltage condition.
Exposed Pad
The exposed pad must be connected to the GND pin for proper
electrical performance. The exposed pad must also be
connected to as much as possible for optimal thermal
performance.
