Overview
LIN D O C #: 1660 LX1660/1661 A DVANCED PWM CONTROLLER T H E I N F I N I T E P O W E R O F I N N O VA T I O N P R O D U C T I O N D A T A S H E E T DESCRIPTION The LX1660 and LX1661 Are Monolithic Switching Regulator Controller ICs designed to provide low-cost, highperformance 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 microprocessors.
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 applications.
Short-Cir cuit Current Limiting Without Expensive Current Sense Resistors.
The current sensing mechanism can use a PCB trace resistance or the parasitic resistance of the main inductor.
For applicat...
