Product Summary

The LTC1430CS is a high power, high efficiency switching regulator controller optimized for 5V to 1.xV-3.xV applications. It includes a precision internal reference and an internal feedback system that can provide output regulation of ±1% over temperature, load current and line voltage shifts. The LTC1430CS uses a synchronous switching architecture with two N-channel output devices, eliminating the need for a high power, high cost P-channel device. The applications of the LTC1430CS include Power Supply for Pentium P6 and Pentium Microprocessors, High Power 5V to 3.xV Regulators, Local Regulation for Dual Voltage Logic Boards, Low Voltage, High Current Battery Regulation.
