PIN FUNCTIONS
SWBST (Pin 1): Switch Pin for the Boost Converter.
Connect the boost inductor between SWBST and V
INBST
.
Keep PCB trace lengths as short and wide as possible to
reduce EMI. If the inductor current falls to zero, an internal
anti-ringing switch is connected from SWBST to V
INBST
to minimize EMI.
V
BST
(Pin 2): Output Voltage for the Boost Converter
(which is the drain of the internal synchronous rectifier)
and Input Voltage for the LDO. PCB trace length from V
BST
to the output filter capacitor (10礔 minimum) should be
as short and wide as possible.
V
LDO
(Pin 3): Output Voltage of the LDO Regulator. Connect
a 1礔 ceramic capacitor between V
LDO
and GND. Larger
values of capacitance may be used for higher PSRR or
improved transient response.
SWBK (Pin 4): Switch Pin for the Buck Converter. Connect
the buck inductor between SWBK and the buck output
filter capacitor. Keep PCB trace lengths as short and wide
as possible to reduce EMI.
V
INBK
(Pin 5): Input Voltage for the Buck Converter. Connect
a minimum of 4.7礔 ceramic decoupling capacitor from
this pin to ground.
PGBK (Pin 6): Open-Drain Output That Pulls Low When
FBBK Is More Than 8% Below Its Regulated Voltage. Con-
nect a pull-up resistor from this pin to a positive supply
less than 6V.
GND (Pin 7): Signal Ground. Provide a short, direct PCB
path between GND and the PC board ground plane con-
nected to the Exposed Pad.
RUNBK (Pin 8): Logic-Controlled Shutdown Input for the
Buck Converter. There is an internal 4M?pull-down on
this pin.
RUNBK = High: Normal operation
RUNBK = Low: Shutdown
FBBK (Pin 9): Feedback Input to the g
m
Error Amplifier
for the Buck Converter. Connect the resistor divider tap
to this pin. The output voltage can be adjusted from 0.6V
to 5.5V by:
