The MLX040A0XY3 Digital DLynxIIITM power

module is a non-isolated dc-dc converter that can

deliver up to 40A of output current. It operates

over a wide input voltage range from 7.0VDC to

14VDC and provides precisely regulated output

voltage programmable from 0.45VDC to 2.0VDC via

PMBusTM. The module employs an advanced PID

based adjustable digital control loop which

ensures loop stability, provides fast transient

response and reduces amount of required output

capacitance. Up to 160A of additional satellite

based phase modules can be connected in parallel

to form a second stand-alone bus. Main features

include: digital PMBusTM interface, programmable

enable logic and control, cycle-by-cycle output

current monitoring, input and output undervoltage

and over-voltage protections, undertemperature

and over-temperature protections

and more. The module has an extensive set of

PMBusTM commands for both control and

monitoring of the system parameters. The

MLX040A0XY3 power module is highly

configurable, and yet easy to use.
