|
P1 is an I2C-controlled PMIC produced by SpacemiT. It implements six
|
|
constant-on-time buck converters and twelve low-dropout regulators.
|
|
It also contains a load switch, watchdog timer, real-time clock, eight
|
|
12-bit ADC channels, and six GPIOs. Additional details are available
|
|
in the "Power Stone/P1" section at the following link.
