Quick-PWM Slave Controller with  
Driver Disable for Multiphase DC-DC Converter  
General Description  
Features  
The MAX1980 step-down slave controller is intended for  
low-voltage, high-current, multiphase DC-DC applica-  
tions. The MAX1980 slave controller can be combined

™
with any of Maxim’s Quick-PWM step-down controllers  
to form a multiphase DC-DC converter. Existing Quick-  
PWM controllers, such as the MAX1718, function as the  
master controller, providing accurate output-voltage regu-  
lation, fast transient response, and fault protection fea-  
tures. Synchronized to the master’s low-side gate driver,  
the MAX1980 includes the Quick-PWM constant on-time  
controller, gate drivers for a synchronous rectifier, active  
current balancing, and precision current-limit circuitry.  
ꢀ Selectable .00kHz/300kHz/220kHz Switching  
Frequency  
ꢀ Drive Large Synchronous-Rectifier MOSFETs  
The MAX1980 provides the same high-efficiency, ultra-  
low duty factor capability, and excellent transient  
response as other Quick-PWM controllers. The MAX1980  
differentially senses the inductor currents of both the  
master and the slave across current-sense resistors.  
These differential inputs and the adjustable current-limit  
threshold derived from an external reference allow the  
slave controller to accurately balance the inductor cur-  
rents and provide precise current-limit protection. The  
MAX1980’s dual-purpose current-limit input also allows  
the slave controller to automatically enter a low-power  
standby mode when the master controller shuts down.

The MAX1980 features a driver-disable mode that forces  
both gate drivers (DL and DH) low. While the MAX1980’s  
drivers are disabled, the master controller can operate in  
low-power skip mode, improving light-load efficiency.  
Additionally, the MAX1980 includes selectable trigger  
polarity, allowing the slave controller to trigger on the ris-  
ing (out-of-phase) or falling (in-phase) edge of the mas-  
ter’s low-side gate driver. Out-of-phase operation  
staggers the master and slave’s on-times, reducing the  
input ripple current and consequently the number of  
input capacitors. The MAX1980 also features a selec-  
table 200kHz/300kHz/550kHz switching frequency. The
