PIN FUNCTIONS
FBLDO (Pin 11): Feedback Input to the g
m
Error Amplifier
for the LDO Regulator. Connect the resistor divider tap to
this pin. The output voltage can be adjusted from 0.6V
to 5.25V by:
V
OUT_LDO
=0.600V" 1+

FBBST (Pin 12): Feedback Input to the g
m
Error Amplifier
for the Boost Converter. Connect the resistor divider tap
to this pin. The output voltage can be adjusted from 1.5V
to 5.25V by:
V
OUT_BOOST
=1.20V" 1+

MODE (Pin 13): Logic-Controlled Mode Select Pin for Both
the Boost and Buck Converters. There is an internal 1M?
pull-up on this pin to the higher of V
INBST
, V
BST
or V
INBK
.
MODE = Float or High: Enables Burst Mode operation for
both the boost and the buck.
MODE = Low: Disables Burst Mode operation. Both con-
verters will operate in fixed frequency mode regardless
of load current.
RUNBST (Pin 14): Logic-Controlled Shutdown Input for
the Boost Converter. There is an internal 4M?pull-down
on this pin.
RUNBST = High: Normal operation
RUNBST = Low: Shutdown
PGBST (Pin 15): Open-Drain Output That Pulls to Ground
When FBBST Is More Than 8% Below Its Regulated Volt-
age. Connect a pull-up resistor from this pin to a positive
supply less than 6V.
V
INBST
(Pin 16): Input Voltage for the Boost Converter.
Connect a minimum of 1礔 ceramic decoupling capacitor
from this pin to ground.
Exposed Pad (Pin 17): The Exposed Pad must be soldered
to the PCB ground plane. It serves as the power ground
connection, and as a means of conducting heat away
from the die.
