5
PGND2
Dedicated Power Ground for BUCK2.
6
NC
No Connect. Do not connect to this pin.
7
EN2
BUCK2 Enable Pin. High level turns on this regulator, and low level turns it off.
8
FB2
BUCK2 Feedback Input. For device models with a factory programmed output voltage, connect FB2 to the top
of the capacitor on VOUT2.
9
VOUT2
BUCK2 Output Voltage Sensing Input. Connect VOUT2 to the top of the capacitor on VOUT2.
10
VOUT1
BUCK1 Output Voltage Sensing Input. Connect VOUT1 to the top of the capacitor on VOUT1.
11
FB1
BUCK1 Feedback Input. For device models with a factory programmed output voltage, connect FB1 to the top
of the capacitor on VOUT1.
12
EN1
BUCK1 Enable Pin. High level turns on this regulator, and low level turns it off.
13
MODE
BUCK1/BUCK2 Operating Mode: MODE = high: forced PWM operation. MODE = low: auto PWM/PSM
operation.
