V C (Pin 1): Compensation Pin for Error Amplifier. V C is
the output of the transconductance error amplifier. Loop
frequency compensation is done by connecting an RC
network from the V C pin to ground.
FB (Pin 2): Inverting Input of the Error Amplifier. Connect
the resistor divider tap here. Set output voltage according
to V OUT = 1.24V (1 + R1/R2).
V OUT (Pin 3): Output of the Switching Regulator and Emit-
ter of the Synchronous Rectifier. Connect appropriate
output capacitor from here to ground. V OUT must be kept
below 5.5V.
GND (Pin 4): Ground. Connect to local ground plane.
SW (Pin 5): Switch Pin. The collectors of the grounded
power switch and the synchronous rectifier. Keep the SW
trace as short as possible to minimize EMI.
BLOCK DIAGRA
CAP (Pin 6): Power Supply to the Synchronous Rectifier
Driver. The bootstrap capacitor and the blocking diode
are tied to this pin. The CAP voltage switches between a
low level of V IN – V D to a high level determined by the V SW
high level.
V IN (Pin 7): Supply or Battery Input Pin. Must be closely
bypassed to ground plane.
S/S (Pin 8): Shutdown and Synchronization Pin. Shut-
down is active low with a typical threshold of 0.9V. For
normal operation, the S/S pin is tied to V IN . To externally
synchronize the switching regulator, drive the S/S pin
with a pulse train.
