AC701 Board Power System

The AC701 board hosts a power system based on the Texas Instruments (TI) UCD90120A
power supply sequencer and monitor, and the TPS84K and LMZ22000 family voltage
regulators.
UCD90120A Description
The UCD90120A is a 12-rail PMBus/I
monitor. The device integrates a 12-bit ADC for monitoring up to 12 power-supply voltage
inputs. Twenty-six GPIO pins can be used for power supply enables, power-on reset
signals, external interrupts, cascading, or other system functions. 12 of these pins offer
PWM functionality. Using these pins, the UCD90120A device offers support for margining
and general-purpose PWM functions.
The UCD90120A device is configured by using the PC-based TI Fusion Digital Power
Designer software. This software provides a graphical user interface (GUI) for configuring,
storing, and monitoring power system operating parameters.
