PIN FUNCTIONS
VOUT1 (Pin 1): Output Voltage Sense and Drain of the
Internal Synchronous Rectier for Channel 1. PCB trace
length from VOUT1 to the output lter capacitor (4.7μF
minimum) should be as short and wide as possible.
SW1 (Pin 2): Switch Pin for Channel 1. Connect inductor
between SW1 and VIN1. Keep PCB trace lengths as short
and wide as possible to reduce EMI. If the inductor current
falls to zero, or SHDN1 is low, an internal anti-ringing switch
is connected from SW1 to VIN1 to minimize EMI.
GND (Pins 3, 6): Signal and Power Ground. Provide a
short direct PCB path between GND and the (-) side of
the input and output capacitors.
VOUT2 (Pin 4): Output Voltage Sense and Drain of the
Internal Synchronous Rectier for Channel 2. PCB trace
length from VOUT2 to the output lter capacitor (4.7μF
minimum) should be as short and wide as possible.
SW2 (Pin 5): Switch Pin for Channel 2. Connect inductor
between SW2 and VIN2. Keep PCB trace lengths as short
and wide as possible to reduce EMI. If the inductor current
falls to zero, or SHDN2 is low, an internal anti-ringing switch
is connected from SW2 to VIN2 to minimize EMI.
VIN2 (Pin 7): Battery Input Voltage for Channel 2. Connect
a minimum of 1μF ceramic decoupling capacitor from this
pin to ground.
SHDN2(Pin8):LogicControlledShutdownInputforChan-
nel 2. There is an internal 4MegΩ pull-down on this pin.
SHDN = High: Normal operation.
SHDN = Low: Shutdown, quiescent current < 1μA.
FB2 (Pin 9): Feedback Input to the gm Error Amplier of
Channel 2. Connect resistor divider tap to this pin. The
output voltage can be adjusted from 1.5V to 5.25V by:
VOUT = 1.195V × [1 + (R4/R3)]
VIN1 (Pin 10): Battery Input Voltage for Channel 1. Connect
a minimum of 1μF ceramic decoupling capacitor from this
pin to ground.
SHDN1(Pin11):LogicControlledShutdownInputforChan-
nel 1. There is an internal 4MegΩ pull-down on this pin.
SHDN = High: Normal operation.
SHDN = Low: Shutdown, quiescent current < 1μA.
FB1 (Pin 12): Feedback Input to the gm Error Amplier
of Channel 1. Connect resistor divider tap to this pin. The
output voltage can be adjusted from 1.5V to 5.25V by:
VOUT = 1.195V × [1 + (R2/R1)]
Exposed Pad (Pin 13): The Exposed Pad must be soldered
to the PCB ground plane. It serves as another ground
connection and as a means of conducting heat away
from the die.
