Dual-Phase, Quick-PWM Controller  
for IMVP6+ CPU Core Power Supplies  
MAX7410  
General Description  
Features  
o Dual-/Single-Phase Interleaved Quick-PWM  
Controller  
The MAX17410 is a 2-/1-phase interleaved Quick-  
PWM™ step-down VID power-supply controller for  
notebook IMVP6+ CPUs. True out-of-phase operation  
reduces input ripple current requirements and output  
voltage ripple while easing component selection and  
layout difficulties. The Quick-PWM control scheme pro-  
vides instantaneous response to fast load current  
steps. Active voltage positioning reduces power dissi-  
pation and bulk output capacitance requirements and  
allows ideal positioning compensation for tantalum,  
polymer, or ceramic bulk output capacitors.  
o ±±0.5 ꢀ

o 7-Bit IMꢀP6+ DAC  
o Dynamic Phase Selection Optimizes Active/Sleep  
Efficiency  
o Transient Phase Overlap Reduces Output  
Capacitance  
o Active ꢀoltage Positioning with Adjustable Gain  
o Accurate Lossless Current Balance  
o Accurate Droop and Current Limit  
o Remote Output and Ground Sense  
o Adjustable Output Slew-Rate Control  
o Power-Good Window Comparator  
o Power Monitor  
The MAX17410 is intended for two different CPU core  
applications: either bucking down the battery directly to  
create the core voltage, or bucking down the +5V sys-  
tem supply. The single-stage conversion method allows  
this device to directly step down high-voltage batteries  
for the highest possible efficiency. Alternatively, 2-stage  
conversion (stepping down the +5V system supply  
instead of the battery) at higher switching frequency  
provides the minimum possible physical size.  
o Programmable Thermal-Fault Protection  
o Phase Fault Output (PHASEGD)  
o Drives Large Synchronous Rectifier FETs  
o 40.ꢀ to 26ꢀ Battery Input Range  
o Output Overvoltage and Undervoltage Protection  
o Soft-Startup and Soft-Shutdown  
o Integrated Boost Switches  
o Low-Profile 7mm x 7mm, 48-Pin TQFN Package  
A slew-rate controller allows controlled transitions  
between VID codes. A thermistor-based temperature  
sensor provides programmable thermal protection. A  
power monitor provides a buffered analog voltage out-  
put proportional to the power delivered to the load.  
The MAX17410 is available in a 48-pin, 7mm x 7mm  
TQFN package.
