KEY FEATURES  
DESCRIPTION  
The LX1660 and LX1661 Are Monolithic Short-Circuit Current Limiting Without  
Switching Regulator Controller ICs designed to Expensive Current Sense Resistors. The  
provide low-cost, high performance adjustable current sensing mechanism can use a PCB trace  
power supply for microprocessors and other resistance or the parasitic resistance of the main  
applications requiring a fast transient response and inductor. For applications requiring a high degree  
a high degree of accuracy. They provide an of accuracy, a conventional sense resistor can be  
adjustable synchronous Pulse Width Modulator used.
