Dual Step-Down Controllers with Saturation  
Protection, Dynamic Output, and Linear Regulator  
General Description  
Features  
♦ Inductor-Saturation Protection  
The MAX1540/MAX1541 dual pulse-width modulation  
(PWM) controllers provide the high efficiency, excellent  
transient response, and high DC-output accuracy nec-  
essary for stepping down high-voltage batteries to gen-  
erate low-voltage chipset and RAM power supplies in  
notebook computers.  
♦ Accurate Differential Current-Sense Inputs  
♦ Dual Ultra-High-Efficiency Quick-PWMs with  
100ns Load-Step Response  
♦ MAX1540  
1.8V/1.2V Fixed or 0.7V to 5.5V Adjustable  
Output (OUT1)  
The Maxim proprietary Quick-PWM™ controllers are  
free running, constant on-time with input feed forward.  
This configuration provides ultra-fast transient  
response, wide input-output (I/O) differential range, low  
supply current, and tight load-regulation characteris-  
tics. The controllers can accurately sense the inductor  
current across an external current-sense resistor in  
series with the output to ensure reliable overload and  
inductor saturation protection. Alternatively, the con-  
trollers can use the synchronous rectifier itself or loss-  
less inductor current-sensing methods to provide  
overload protection with lower power dissipation.  
2.5V/1.5V Fixed or 0.7V to 5.5V Adjustable  
Output (OUT2)  
Fixed 5V, 100mA Linear Regulator  
♦ MAX1541  
External Reference Input (REFIN1)  
Dynamically Selectable Output Voltage—0.7V  
to 5.5V (OUT1)  
2.5V/1.8V Fixed or 0.7V to 5.5V Adjustable  
Output (OUT2)  
Optional Power-Good and Fault Blanking  
During Transitions  
Fixed 5V or Adjustable 100mA Linear Regulator  
For a single step-down PWM controller with inductor-  
saturation protection, external-reference input voltage,  
and dynamically selectable output voltages, refer to the  
MAX1992/MAX1993 data sheet.  
♦ 1% V  
Accuracy over Line and Load  
OUT  
♦ 2V to 28V Battery Input Range  
♦ 170kHz to 620kHz Selectable Switching  
Frequency  
Applications  
♦ Overvoltage/Undervoltage-Protection Option  
♦ 1.7ms Digital Soft-Start  
Notebook Computers  
Core/IO Supplies as Low as 0.7V  
0.7V to 5.5V Supply Rails  
♦ Drives Large Synchronous-Rectifier FETs  
♦ 2V 0.7% Reference Output  
♦ Separate Power-Good Window Comparators
