EVALUATION KIT AVAILABLE  
MAX16930/MAX16931  
2MHz, 36V, Dual Buck with Preboost and  
20µA Quiescent Current  
General Description  
Features  
The MAX16930/MAX16931 offer two high-voltage,  
synchronous step-down controllers and a step-up  
preboost controller. They operate with an input voltage  
supply from 2V to 42V with preboost active and can oper-  
ate in drop-out condition by running at 95% duty cycle.  
The devices are intended for applications with mid- to  
high-power requirements that operate at a wide input  
voltage range such as during automotive cold-crank or  
engine stop-start conditions.  
S Dual, 2MHz Step-Down Controllers  
S Preboost for Operation to 2V  
S 180° Out-of-Phase Operation  
S 50ns Minimum On-Time Allows 3.3V Output from  
Car Battery at 2.2MHz  
S 20µA Operating Current  
S Wide Input Supply Range from 3.5V to 36V (with-  
out Preboost)  
The MAX16930/MAX16931 step-down controllers oper-  
ate 180N out-of-phase at frequencies up to 2.2MHz to  
allow small external components, reduced output ripple,  
and to guarantee no AM band interference. The switch-  
ing frequency is resistor adjustable. The FSYNC input  
programmability enables three frequency modes for  
optimized performance: forced fixed-frequency opera-  
tion, skip mode with ultra-low quiescent current (20FA),  
and synchronization to an external clock. The devices  
also provide a spread-spectrum option to minimize EMI  
interference.  
S Resistor Programmable Frequency Between  
200kHz and 2.2MHz  
S Q1% Output-Voltage Accuracy: 5.0V/3.3V Fixed or  
Adjustable Between 1V and 10V  
S Current-Mode Controllers with Forced Continuous  
and Skip Modes  
S Frequency Synchronization Input  
S Supply Overvoltage and Undervoltage Lockout  
S Overtemperature and Short-Circuit Protection  
The MAX16930/MAX16931 are offered with an asynchro-  
nous step-up controller. This preboost circuitry turns on  
during low input voltage conditions. It is designed to pro-  
vide power to step-down controller channels with input  
voltages as low as 2V.  
S Thermally Enhanced 40-Pin TQFN-EP and Side-  
Wettable QFND-EP Packages  
S -40NC to +125NC Operating Temperature  
Applications  
The devices also feature a power-OK monitor and  
overvoltage and undervoltage lockout. Protection  
features include cycle-by-cycle current limit and thermal  
shutdown.  
POL Applications for Automotive Power  
Distributed DC Power Systems  
Navigation and Radio Head Units  
The devices are available in 40-pin TQFN-EP and side-  
wettable QFND-EP packages and are specified for oper-  
ation over the -40NC to +125NC automotive temperature  
range.
