Product Summary

The LX1660CD is a Monolithic Switching Regulator Controller IC 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. The LX1660CD provides an adjustable synchronous Pulse Width Modulator output suitable for a power supply for Pentium or other microprocessors.The LX1660CD 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 applications. The typical applications of LX1660CD include: (1)Pentium Processor Supplies; (2)AMD-K6TM Supplies; (3)Cyrix 6x86TM Supplies; (4)Voltage Regulator Modules; (5)General Purpose DC:DC Supplies.

Parametrics

LX1660CD absolute maximum ratings: (1)Supply Voltage: 25V; (2)Output Peak Current Source (500ns): 1.5A; (3)Output Peak Current Sink (500ns): 1.5A; (4)Analog Inputs: -0.3 to +6V; (5)Power Dissipation at TA = 25℃: 830mW; (6)Operating Junction Temperature Plastic (N, D Packages): 150℃; (7)Storage Temperature Range: -65℃ to +150℃; (8)Lead Temperature (Soldering, 10 Seconds): 300℃; (9)Peak Package Solder Reflow Temp. (40 second max. exposure): 260℃ (+0, -5).

Features

LX1660CD features: (1)Designed To Drive A Synchronous Rectifier Stage-Can Also Be Used In Non-Synchronous Applications; (2)Soft-Start Capability; (3)Hiccup-Mode Fault Protection; (4)No Current-Sense Resistor Required For Current Limiting; (5)Modulated Constant Off-Time Control Mechanism For Fast; (6)Transient Response And Simple System Design; (7)2V, 0.5% Internal Voltage Reference Brought Out.
