Quick-PWM Step-Down Controllers with Inductor  
Saturation Protection and Dynamic Output Voltages  
General Description  
Features  
The MAX1992/MAX1993 pulse-width modulation (PWM)  
controllers provide high-efficiency, excellent transient  
response, and high DC output accuracy. The devices  
step down high-voltage batteries to generate low-  
voltage CPU core or chipset/RAM supplies in notebook  
computers.  
♦ Inductor Saturation Protection  
♦ Accurate Current Limit  
♦ Ultra-High Efficiency  
♦ Quick-PWM with 100ns Load-Step Response  
♦ MAX1992  
Maxim’s proprietary Quick-PWM™ quick-response, con-  
stant on-time PWM control scheme handles wide  
input/output voltage ratios with ease and provides 100ns  
“instant-on” response to load transients, while maintaining  
a relatively constant switching frequency. Efficiency is  
enhanced by the ability to drive very large synchronous-  
rectifier MOSFETs. Current sensing to ensure reliable  
overload and inductor saturation protection is available  
using an external current-sense resistor in series with the  
output. Alternatively, the controller can sense the current  
across the synchronous rectifier alone or use lossless  
inductor sensing for lowest power dissipation.

♦ Overvoltage/Undervoltage Protection Option  
♦ 1.7ms Digital Soft-Start  
♦ Drives Large Synchronous Rectifier FETs  
♦ 2V 0.7ꢀ Reference Output  
Single-stage buck conversion allows the MAX1992/  
MAX1993 to directly step down high-voltage batteries for  
the highest possible efficiency. Alternatively, two-stage  
conversion (stepping down from another system supply  
rail instead of the battery) at the maximum switching fre-  
quency allows the minimum possible physical size.  
♦ Power-Good Window Comparator  
The MAX1992 powers the CPU core, chipset, DRAM, or  
other supply rails as low as 0.7V. The MAX1993 powers  
chipsets and graphics processor cores, which require  
dynamically adjustable output voltages. The MAX1993  
provides a tracking input that can be used for active ter-  
mination buses. The MAX1992/MAX1993 are available in  
a 24-pin thin QFN package with optional overvoltage and  
undervoltage protection.
