General Description
The MAX16064 is a fully integrated 4-channel digital
power-supply controller and monitor IC that can be con-
nected up to four power supplies to provide complete
digital configurability. By interfacing to the power-supply
reference input or feedback node, and the output enable,
the MAX16064 takes control of the power supply to pro-
vide tracking, soft-start, sequencing, margining, and
dynamic adjustment of the output voltage.
Power-supply sequencing can be performed
autonomously or controlled over the PMBus™ interface.
Sequencing is controlled during power-down as well as
power-up. Multiple MAX16064s can be combined to
autonomously sequence more supplies. The sequencing
order is stored in an external configuration EEPROM so
sequence order changes can be reprogrammed without
changing the PCB layout.
The MAX16064 features an internal temperature sensor
providing an additional level of system monitoring.
Other features include a reset output and an SMBus™
alert output.
Each channel of the MAX16064 includes an accurate
12-bit analog-to-digital converter (ADC) input and a differen-
tial amplifier for accurately monitoring and reporting the volt-
age at the load without being influenced by any difference in
ground potentials. An integrated 12-bit digital-to-analog con-
verter (DAC) can margin power supplies and dynamically
adjust the output voltage using a closed-loop control system
to provide an output-voltage accuracy of ±0.3%.
The user-programmable registers provide flexible and
accurate control of time events such as delay time and
transition period, monitoring for overvoltage and under-
voltage, overtemperature fault and warning handling.
The closed-loop operation is also programmable to make
sure the MAX16064 works with any existing power sup-
ply to provide superior regulation accuracy and accurate
margining.
The MAX16064 operates using a PMBus-compliant com-
munication protocol. The device can be programmed
using this protocol or with a free graphic-user interface
(GUI) available from the Maxim website that significantly
reduces development time. Once the configuration is
complete, the results can be saved into an EEPROM or
loaded into the device through PMBus at power-up. This
allows remote configuration of any power supply using
the MAX16064, replacing expensive recalls or field ser-
vice. The MAX16064 can be programmed with up to 114
distinct addresses to support large systems. The
MAX16064 is offered in a space-saving, 36-pin, lead-free,
6mm x 6mm TQFN package and is fully specified from
-40°C to +85°C.
