PIN FUNCTIONS
VIN(Pin14/Pin10):MainSupplyInput.Thesupplyvoltage
can range from 4.5V to 38V. For increased noise immunity
decouple this pin to signal ground with an RC filter. The
voltage on this pin is also used to adjust the TG on-time
in order to maintain constant frequency operation.
INTVCC (Pin 15/Pin 11): Internal 5.3V Regulator Output.
The driver and control circuits are powered from this volt-
age. Decouple this pin to power ground with a minimum of
4.7μF ceramic capacitor (CVCC).TheanodeoftheSchottky
diode, DB, connects to this pin.
PGND(Pin16/Pin12):PowerGroundConnection.Connect
this pin as close as practical to the source of the bottom
N-channel power MOSFET, the (–) terminal of CVCC and
the (–) terminal of CIN.
BG (Pin 17/Pin 13): Bottom Gate Drive Output. This pin
drives the gate of the bottom N-channel power MOSFET
between INTVCC and power ground.
SW (Pin 18/Pin 14): Switch Node Connection. The (–)
terminal of the bootstrap capacitor, CB, connects to this
node. This pin swings from a diode voltage below ground
up to VIN.
TG (Pin 19/Pin 15): Top Gate Drive Output. This pin drives
the gate of the top N-Channel power MOSFET between
VSW and VBOOST.
BOOST (Pin 20/Pin 16): Boosted Driver Supply Connec-
tion. The (+) terminal of the bootstrap capacitor, CB, as
well as the cathode of the Schottky diode, DB, connects
to this node. This node swings from INTVCC – VSCHOTTKY
to VIN + INTVCC – VSCHOTTKY.
SGND (Exposed Pad Pin 21/Exposed Pad Pin 21): Signal
Ground Connection. The SGND exposed pad must be
soldered to the circuit board for electrical contact and
rated thermal performance. All small-signal components
should be connected to the signal ground. Connect signal
ground to power ground only at one point using a single
PCB trace.
