TERMINAL FUNCTIONS
TERMINAL
I/O
DESCRIPTION
NAME
NO.
Enable. A logic high enables the converter; logic low forces the device into shutdown mode reducing the
EN
4
I
supply current to less than 2 A.
Feedback pin for the fixed output voltage option. For the adjustable version, an external resistive divider
FB
10
I
is connected to this pin. The internal voltage divider is disabled for the adjustable version.
LBO
6
O
Open-drain, low-battery output. This pin is pulled low if LBI is below its threshold.
GND
11, 12
I
Ground
LBI
7
I
Low-battery input
Connect the inductor to this pin. This pin is the switch pin and connected to the drain of the internal
SW

O
power MOSFETS.
Power good comparator output. This is an open-drain output. A pullup resistor should be connected
PG

O
between PG and VOUT. The output goes active high when the output voltage is greater than 98.4% of
the nominal value.
PGND
1, 16
I
Power ground. Connect all power grounds to this pin.
AGND
9
I
Analog ground, connect to GND and PGND
Input for synchronization to external clock signal. Synchronizes the converter switching frequency to an
external clock signal with CMOS level:
SYNC
5
I
SYNC = HIGH: Low-noise mode enabled, fixed frequency PWM operation is forced
SYNC = LOW (GND): Power save mode enabled, PFM/PWM mode enabled
VIN
2, 3
I
Supply voltage input (power stage)
VINA
8
I
Supply voltage input (support circuits)
PowerPAD
Connect to AGND
