FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
REG2 BUCK STAGE SWITCHING NODE (SW2D)
The inductor is connected between this pin and the SW2U
pin.
REG2 REGULATED OUTPUT VOLTAGE PIN
(VOUT2)
Connect this pin to the load and to the output filter as close
to the pin as possible.
REG2 BOOST STAGE SWITCHING NODE (SW2U)
The inductor is connected between this pin and the SW2D
pin.
REG5 BOOST STAGE SWITCHING NODE (SW5U)
The inductor is connected between this pin and the SW5D
pin.
REG5 REGULATED OUTPUT VOLTAGE PIN
(VOUT5)
Connect this pin to the load and to the output filter as close
to the pin as possible.
REG5 BUCK STAGE SWITCHING NODE (SW5D)
The inductor is connected between this pin and the SW5U
pin.
REG5 POWER SUPPLY INPUT VOLTAGE (PVIN5)
This is the connection to the drain of the high side switch
FET. Input decoupling /filtering is required for proper REG5
operation.
REG5 BUCK STAGE BOOTSTRAP CAPACITOR
INPUT PIN (BT5D)
Connect a 1
F capacitor between this pin and SW5D pin
to enhance the gate of the Switch Power MOSFET.
REG5 VOLTAGE FEEDBACK INPUT FOR
VOLTAGE REGULATION/PROGRAMMING (FB5)
Connect the feedback resistor divider to this pin.
REG5 COMPENSATION NETWORK CONNECTION
(COMP5)
REG5 compensation network connection.
POWER GROUND CONNECTION FOR ALL OF THE
REGULATORS EXCEPT REG7 (PGND)
Power Ground Connection for all of the regulators except
REG7.
