Fe a t u re s  
The MAX8543/MAX8544 current-mode, constant-fre-  
quency PWM buck controllers operate from a 3V to  
13.2V input supply and generate adjustable 0.8V to 0.9  
Prebias Startup/Monotonic  
1% Output Accuracy  
x V output voltages at loads up to 25A. They feature  
adjustable switching frequency and synchronization for  
noise-sensitive applications.

200kHz to 1MHz Adjustable Frequency  
160kHz to 1.2MHz Synchronization  
Lossless, Foldback Current Limit  
Overvoltage Protection  
The MAX8543/MAX8544 can start with (or without) a pre-  
existing bias on the output, without discharging the out-  
put. This feature simplifies tracking supply designs for  
core and I/O applications and redundant supply designs.  
The MAX8543/MAX8544 use the DC resistance of the  
output inductor as the current-sense element for loss-  
le s s , low-c os t c urre nt s e ns ing . The c urre nt-s e ns e  
threshold can be set to four discrete levels to accom-  
modate inductors with different DC resistance values.

Adjustable Soft-Start  
MAX8544  
Latch-Off/Autorecovery  
Power-OK Monitor  
Out-of-Phase Clock Output  
The MAX8544 features a power-OK monitor and two  
MAX8544 controllers that can operate at 180° out-of-  
phase for dual-output applications.
