DESCRIPTION  
KEY FEATURES  
■ Designed To Drive A Synchronous Rectifier  
The LX1660 and LX1661 Are Mono-  
lithic Switching Regulator Controller  
ICs designed to provide low-cost, high-  
performance adjustable power supply for  
microprocessors and other applications  
requiring a fast transient response and a  
high degree of accuracy. They provide  
an adjustable synchronous Pulse Width  
Modulator output suitable for a power  
supply for Pentium® or other micropro-  
cessors.  
Synchronous Rectifier Driver For  
CPU Core. The devices can drive dual  
MOSFETs resulting in typical efficiencies  
of 85 - 90%, even with loads in excess of  
10A. Synchronous shutdown results in  
increased efficiency in light load applica-  
tions.  
Short-Circuit Current Limiting  
Without Expensive Current Sense Re-  
Stage — Can Also Be Used In Non-  
Synchronous Applications  
■ Soft-Start Capability  
■ Hiccup-Mode Fault Protection  
■ No Current-Sense Resistor Required For  
Current Limiting  
■ Modulated Constant Off-Time Control  
Mechanism For Fast Transient Response And  
Simple System Design  
sistors. The current sensing mechanism  
can use a PCB trace resistance or the para-  
sitic resistance of the main inductor. For  
applications requiring a high degree of  
accuracy, a conventional sense resistor  
can be used.  
Hiccup Mode Fault Protection. The  
hiccup mode is programmable and with  
pulse-by-pulse current limiting will help  
protect the power supply system and load  
in the even of a short circuit.  
Ultra-Fast Transient Response Re-  
duces System Cost. The fixed frequency  
modulated off-time architecture results in  
the fastest transient response for a given  
inductor. Adaptive voltage positioning  
(LX1661 only) requires fewer low-ESR ca-  
pacitors to meet stringent transient over-  
and under-shoot specifications.  
■ 2V, 0.5% Internal Voltage Reference Brought  
Out  
APPLICATIONS  
■ Pentium Processor Supplies  
■ AMD-K6TM Supplies  
■ Cyrix® 6x86TM Supplies  
■ Voltage Regulator Modules  
■ General Purpose DC:DC Supplies
