Chapter 1:

ML628 Board Features and Operation

The ML628 board uses power regulators and PMBus compliant digital PWM system 
controllers from Texas Instruments to supply the core and auxiliary voltages listed in 

Table 1-1

. The board can also be configured to use external bench power supply for each 

voltage. See 

Using External Power Sources

.

Using External Power Sources

The maximum output current rating for each power regulator is listed in 

Table 1-1

. If a 

design exceeds this value on any power rail, power for that rail must be supplied through 
the external power jack using a supply capable of providing the required current.

Each power rail has a corresponding jack and jumper that is used to supply voltage to the 
rail using an external power supply. The jack, jumper, and regulator for each power rail is 
listed in 

Table 1-1

.

Caution!

The power regulation jumper (see 

Power Regulation Jumper

 column in

Table 1-1

) 

must be removed before applying external power to the power rail through its corresponding 
supply jack.

Caution!

The external power supply jacks have a maximum current rating of 15A.
