Product Summary

The LX1662ACD is a Monolithic Switching Regulator Controller IC designed to provide a low cost, high performance adjustable power supply for advanced microprocessors and other applications requiring a very fast transient response and a high degree of accuracy. The LX1662ACD has reduced current sense comparator threshold for optimum performance using a PCB trace. For applications requiring a high degree of accuracy, a conventional sense resistor can be used to sense current. The typical applications of LX1662ACD include: (1)Socket 7 Microprocessor Supplies (including Intel Pentium Processor, AMDK6TM And Cyrix?6x86TM, Gx86TM and M2TM; (2)Processors); (3)Pentium II and Deschutes Processor & L2-Cache Supplies; (4)Voltage Regulator Modules; (5)General Purpose DC:DC Converter Applications.

Parametrics

LX1662ACD absolute maximum ratings: (1)Supply Voltage (VC1): 25V; (2)Supply Voltage (VCC): 15V; (3)Output Drive Peak Current Source (500ns): 1.5A; (4)Output Drive Peak Current Sink (500ns): 1.5A; (5)Input Voltage (SS, INV, VCC_CORE, CT, VID0-VID4): -0.3V to 6V; (6)Operating Junction Temperature Plastic (N & D Packages): 150℃; (7)Storage Temperature Range: -65℃ to +150℃; (8)Lead Temperature (Soldering, 10 Seconds): 300℃.

Features

LX1662ACD features: (1)5-bit Programmable Output For CPU Core Supply; (2)No Sense Resistor Required For Short-Circuit Current Limiting; (3)Designed To Drive Either Synchronous Or Non-Synchronous Output Stages; (4)Lowest System Cost Possible For Price-Sensitive Pentium And Pentium II Class Applications; (5)Soft-Start Capability; (6)Modulated, Constant Off-Time Architecture For Fast Transient Response And Simple System Design; (7)Small, Surface-Mount Packages.
