Dual Quick-PWM, Step-Down Controller  
with Low-Power LDO, RTC Regulator  
MAX701  
General Description  
Features  
The MAX17101 is a dual Quick-PWM™ step-down  
power-supply (SMPS) controller with synchronous rectifi-  
cation, intended for main 5V/3.3V power generation in  
battery-powered systems. Low-side MOSFET sensing  
provides a simple low-cost, highly efficient current sense  
for providing valley current-limit protection. Combined  
with the output overvoltage and undervoltage protection  
features, this current limit ensures robust output supplies.  
o Dual Quick-PWM  
o Internal 100mA 5V or Adjustable Linear Regulator  
o Independent LDO Bypass Input  
o Internal Boost Diodes  
o Secondary Feedback Input Maintains Charge Pump  
o 3.3V 5mA RTC Power (Always On)  
o OUT1: 5V or 1.5V Fixed or 0.7V Adjustable  
Feedback  
o OUT2: 3.3V or 1.05V Fixed or Dynamic Adjustable  
o Dynamic 0 to 2V REFIN2 Input on Second Output  
o 2V 1ꢀ 50ꢁA Reference  
The 5V/3.3V SMPS outputs can save power by operating  
in pulse-skipping mode or in ultrasonic mode to avoid  
audible noise. Ultrasonic mode forces the controller to  
maintain switching frequencies greater than 20kHz at  
light loads.  
o 6V to 24V Input Range (28V max)  
o Ultrasonic Mode  
An internal 100mA linear regulator can be used to  
either generate the 5V bias needed for power-up or  
other lower power “always-on” suspend supplies. An  
independent bypass input allows automatic bypassing  
of the linear regulator when the SMPS is active.  
o Independent SMPS and LDO Enable Controls  
o Independent SMPS Power-Good Outputs  
o Minimal Component Count  
This main controller also includes a secondary feed-  
back input that triggers an ultrasonic pulse (DL1 turned  
on) if the SECFB voltage drops below its threshold volt-  
age. This refreshes an external charge pump driven by  
DL1 without overcharging the output voltage.

The device includes independent shutdown controls to  
simplify power-up and power-down sequencing. To  
prevent current surges at startup, the internal voltage  
target is slowly ramped up from zero to the final target  
over a 1ms period. To prevent the output from ringing  
below ground in shutdown, the internal voltage target  
is ramped down from its previous value to zero over a  
1ms period. Two independent power-good outputs  
simplify the interface with external controllers.
