1
FB
Feedback. Input to the error amplifier. Connect to the external resistor divider
network to set the output voltage.
2
VIN
Supply Voltage (Input): Supply voltage for the internal switches and drivers.
3
LOWQ
Enable LDO Mode (Input): Logic low enables the internal LDO and disables the
PWM operation. Logic high enables the PWM mode and disables the LDO
mode.
4
EN
Enable (Input). Logic low will shut down the device, reducing the quiescent
current to less than 5

GND
Switch (Output): Internal power MOSFET output switches before Inductor
Power Ground. Requires input capacitor to GND.
12
AVIN
Analog Supply Voltage (Input): Supply voltage for the analog control circuitry and
LDO input power. Requires bypass capacitor to GND.
13
LDO
LDO Output (Output): Connect to V
OUT
for LDO mode operation.
Internal circuit bias supply. Must be de-coupled to signal ground with a 0.1
