Digital Power-Supply Controller/Monitor  
with PMBus Interface  
MAX68  
General Description  
Features  
The MAX8688 fully integrated digital power-supply con-  
troller and monitor IC works with any existing POL  
(point-of-load) power supply to provide complete digital  
programmability. By interfacing to the reference input,  
feedback node, and output enable, the MAX8688 takes  
control of the POL to provide functions such as perfect  
tracking, sequencing, margining, and dynamic adjust-  
ment of the output voltage.  
o PMBus Interface for Programming, Monitoring,  
Sequencing Up and Down, and Accurate Output-  
Voltage Control  
o Controls Output Voltage with 0.2% Accuracy for  
Line, Load, and Temperature Variations  
o Output Voltage, Output Current, and Temperature  
Monitoring with Adjustable Monitor Rate  
o Current Measurement with 2.6% Accuracy and  
The MAX8688 offers an accurate 12-bit analog-to-digi-  
tal converter (ADC) accompanied with two differential  
amplifiers for accurately monitoring both voltage and  
current. An integrated 12-bit digital-to-analog converter  
(DAC) is also available to margin power supplies as  
well as dynamically adjust the output voltage with 0.2%  
accuracy over temperature using this closed-loop sys-  
tem. An internal temperature sensor provides an addi-  
tional level of system monitoring.  
Temperature Compensation Option  
o Programmable Soft-Start and Soft-Stop Ramp  
Rates  
o Controls Up to 26 Power Supplies with Hardwired  
Address Pins and Up to 127 POLs with Software  
Addressing  
o Compatible with REFIN and FB Terminals of POL  
Power Supplies  
The user-programmable registers provide flexible and  
accurate control of time events such as a delay time  
and transition period, monitoring for overvoltage and  
undervoltage, overcurrent, reverse-current, overtemper-  
ature fault and warning handling. The closed-loop oper-  
ation is also programmable to make sure the MAX8688  
works with any existing POL to provide superior regula-  
tion accuracy and accurate margining.  
o Protection for POL Against Overvoltage,  
Undervoltage, Overcurrent, Negative Current and  
Overtemperature Faults with No Action, Latch and  
Retry (Hiccup) Options  
o Open-Drain FLT Signal for Fault Detection  
o Master-Slave Clocking Option Eliminates External  
Clock Requirement and Provides Accurate Timing  
Reference  
The MAX8688 operates using a PMBus™-compliant  
communication protocol. The device is programmed  
using this protocol or simply with the use of 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 onto the part through  
the PMBus at power-up. This allows remote configura-  
tion of any POL using the MAX8688, replacing expen-  
sive recalls or field service. Module current sharing is  
also supported, since accurate current measurement  
and fine resolution voltage control are available. The  
MAX8688 can be programmed with up to 127 distinct  
addresses to support large systems. The MAX8688 is  
offered in a space-saving, 24-pin, lead-free 4mm x  
4mm TQFN package.  
o External EEPROM Interface for Auto-Programming  
on Power-Up
