Description
1
BST3
High-Side FET Driver Power Supply for Channel 3.
2
PGND3
Power Ground for Channel 3.
3
SW3
Switching Node Output for Channel 3.
4
PVIN3
Power Input for Channel 3. Connect a bypass capacitor between this pin and ground.
5
EN5
Enable Input for Channel 5. An external resistor divider can be used to set the turn-on threshold.
6
FB5
Feedback Sensing Input for Channel 5.
7
VOUT5
Power Output for Channel 5.
8
PVIN5
Power Input for Channel 5. Connect a bypass capacitor between this pin and ground.
9
PVIN4
Power Input for Channel 4. Connect a bypass capacitor between this pin and ground.
10
SW4
Switching Node Output for Channel 4.
11
PGND4
Power Ground for Channel 4.
12
BST4
High-Side FET Driver Power Supply for Channel 4.
13
nINT
Interrupt Output on Fault Condition. Open-drain output port.
14
EN4
Enable Input for Channel 4. An external resistor divider can be used to set the turn-on threshold.
15
COMP4
Error Amplifier Output for Channel 4. Connect an RC network from this pin to ground.
16
FB4
Feedback Sensing Input for Channel 4.
17
VDDIO
Power Supply for the I2C Interface.
18
SDA
Data Input/Output for the I2C Interface. Open-drain I/O port.
19
SCL
Clock Input for the I2C Interface.
20
PWRGD
Power-Good Signal Output. This open-drain output is the power-good signal for the selected channels.
This pin can be programmed by the factory to set the I2C address of the part; the I2C address setting function
replaces the power-good function on this pin. For more information, see the I2C Addresses section.
21
FB2
Feedback Sensing Input for Channel 2.
22
COMP2
Error Amplifier Output for Channel 2. Connect an RC network from this pin to ground.
23
EN2
Enable Input for Channel 2. An external resistor divider can be used to set the turn-on threshold.
24, 25
PVIN2
Power Input for Channel 2. Connect a bypass capacitor between this pin and ground.
26, 27
SW2
Switching Node Output for Channel 2.
28
BST2
High-Side FET Driver Power Supply for Channel 2.
29
DL2
Low-Side FET Gate Driver for Channel 2. Connect a resistor from this pin to ground to program the current-limit
threshold for Channel 2.
