Pin Descriptions
Pin #
Pin Name
Pin Function
1
LX1
Switching (phase) node for VOUT1
2
BST1
Boost capacitor connection for VOUT1 high-side gate drive
3
VDD1
5V supply input for VOUT1 analog circuits and gate drive outputs. Under-voltage lockout for the 5V supply is
sensed on VDD1 only.
4
DL1
Gate drive output for the VOUT1 low-side external MOSFET
5
EN1
Enable input for VOUT1. Ground to disable the VOUT1 switcher. Leave open to enable VOUT1 switcher with
power-save disabled. Connect to VDD1 to enable VOUT1 in power-save mode.
6
SS1
Soft-start input for VOUT1. For independent start-up, connect a capacitor to RTN.
7
VOUT1
Connect to the output capacitor of VOUT1. Used for DH1 On-Time generation, and for VOUT1 regulation when
FB1 is connected to VDD1 or RTN.
8
FB1
Feedback input for VOUT1. Connect to an external resistor divider to adjust VOUT1, or connect to RTN or VDD1
to select internal feedback resistors via the VOUT1 pin.
9
RTN
Analog return (ground) for both VOUT1 and VOUT2
10
TON
On-time adjust input. Connect a resistor from VIN to TON to program the on-time. The on-time one-shot for
VOUT1 is internally set at 20% greater than for VOUT2, to prevent frequency interaction between the two con-
verters.
11
FB2
Feedback input for VOUT2. Connect to an external resistor divider to adjust VOUT2, or connect to RTN or VDD2
to select internal feedback resistors via the VOUT2 pin.
12
VOUT2
Connect to the output capacitor of VOUT2. Used for side 2 On-Time generation, and for VOUT2 regulation when
FB2 is connected to VDD2 or RTN.
13
SS2
Soft-start input for VOUT1. For independent start-up, connect a capacitor to RTN.
14
EN2
Enable input for VOUT2. Ground to disable the VOUT2 switcher. Leave open to enable VOUT2 switcher with
power-save disabled. Connect to VDD2 to enable VOUT2 in power-save mode.
15
DL2
Gate drive output for the VOUT2 low-side external MOSFET
16
VDD2
5V supply input for VOUT2 analog circuits and gate drive outputs. VDD2 must connect to the same supply as
VDD1.
17
BST2
Boost capacitor connection for VOUT2 high-side gate drive
18
LX2
Switching (phase) node for VOUT2
19
DH2
Gate drive output for the VOUT2 high-side external MOSFET
20
ILIM2
Current limit input for VOUT2. Connect through a resistor to the drain of the VOUT2 low-side MOSFET.
21
PGD2
Open-drain Power Good output for VOUT2
22
PGD1
Open-drain Power Good output for VOUT1
23
ILIM1
Current limit input for VOUT1. Connect through a resistor to the drain of the VOUT1 low-side MOSFET.
24
DH1
Gate drive output for the VOUT1 high-side external MOSFET
T
PAD
Power ground for VOUT1 and VOUT2 gate drivers, and thermal pad for heatsinking
