Description
1
PGOOD1
Power-Good Output (Open Drain) for Channel 1. A pull-up resistor of 10 kΩ to 100 kΩ is recommended.
2
SCFG
Synchronization Configuration Input. The SCFG pin configures the SYNC pin as an input or output. Connect
SCFG to INTVCC to configure SYNC as an output. Using a resistor to pull down to GND configures SYNC as an
input with various phase shift degrees.
3
SYNC
Synchronization. This pin can be configured as an input or an output. When configured as an output, it
provides a clock at the switching frequency. When configured as an input, this pin accepts an external clock
to which the regulators are synchronized and the phase shift is configured by SCFG. Note that when SYNC is
configured as an input, the PFM mode is disabled and the device works only in continuous conduction mode
(CCM).
4
GND
Analog Ground. Connect to the ground plane.
5
INTVCC
Internal 5 V Regulator Output. The IC control circuits are powered from this voltage. Place a 1 μF ceramic
capacitor between INTVCC and GND.
6
RT
Connect a resistor between RT and GND to program the switching frequency between 250 kHz and 1.2 MHz.
7
MODE
Mode Selection. When this pin is connected to INTVCC, the PFM mode is disabled and the regulator works
only in CCM. When this pin is connected to ground, the PFM mode is enabled. If the low-side device is a
diode, the MODE pin must be connected to ground.
8
PGOOD2
Power-Good Output (Open Drain) for Channel 2. A pull-up resistor of 10 kΩ to 100 kΩ is recommended.
9
FB2
Feedback Voltage Sense Input for Channel 2. Connect to a resistor divider from the Channel 2 output voltage,
VOUT2. Connect FB2 to INTVCC for parallel applications.
10
COMP2
Error Amplifier Output for Channel 2. Connect an RC network from COMP2 to GND. Connect COMP1 and
COMP2 together for parallel applications.
11
SS2
Soft Start Control for Channel 2. Connect a capacitor from SS2 to GND to program the soft start time. For
parallel applications, SS2 remains open.
12
TRK2
Tracking Input for Channel 2. To track a master voltage, drive this pin from a voltage divider from the master
voltage. If the tracking function is not used, connect TRK2 to INTVCC.
13
EN2
Enable Pin for Channel 2. An external resistor divider can be used to set the turn-on threshold. When not
using the enable pin, connect EN2 to PVIN2.
14, 15
PVIN2
Power Input for Channel 2. Connect PVIN2 to the input power source, and connect a bypass capacitor
between PVIN2 and ground.
16, 17
SW2
Switch Node for Channel 2.
18
BST2
Supply Rail for the Gate Drive of Channel 2. Place a 0.1 μF capacitor between SW2 and BST2.
19
DL2
Low-Side Gate Driver Output for Channel 2. Connect a resistor between DL2 and PGND to program the
current-limit threshold of Channel 2.
20
VDRV
Low-Side Driver Supply Input. Connect VDRV to INTVCC. Place a 1 μF ceramic capacitor between the VDRV
pin and PGND.
21
PGND
Driver Power Ground. Connect to the source of the synchronous N-channel MOSFET.
22
DL1
Low-Side Gate Driver Output for Channel 1. Connect a resistor between this pin and PGND to program the
current-limit threshold of Channel 1.
