PIN FUNCTIONS
Pin #
Name
Description
1
FB1
Feedback of buck 1. Connect b
uck 1’s output directly to this pin.
2
PWRON
Power-on/off input. Logic input pin to start up or shut down the device. This pin should be
pulled high by an external voltage.
3
VIN1
Buck 1 supply voltage input. The MPQ7920 operates from a 2.7V to 5.5V input rail. It
requires a ceramic capacitor to decouple the input rail. Connect using a wide PCB trace.
VIN1, VIN2, VIN3, VIN4, and AVIN must be connected to the same bus voltage.
4
SW1
Buck 1 switch output. Connect using a wide PCB trace.
5
GND1
Buck 1 and buck 3 power ground. Requires special consideration during PCB layout.
Connect to GND with copper traces and vias.
6
SW3
Buck 3 switch output. Connect using a wide PCB trace.
7
VIN3
Buck 3 supply voltage input. The MPQ7920 operates from a 2.7V to 5.5V input rail. It
requires a ceramic capacitor to decouple the input rail. Connect using a wide PCB trace.
VIN1, VIN2, VIN3, VIN4, and AVIN must be connected to the same bus voltage.
8
FB3
Buck 3 feedback. Directly connect buck
3’s output to this pin.
9
RSTO
Reset output from the PMIC to CPU. Open-drain output. This pin requires an external pull-
up resistor.
10
SCL
I2C clock signal input.
11
SDA
I2C data pin.
