Product Summary
The LTC1430ACGN#TR 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 LTC1430ACGN#TR 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 LTC1430ACGN#TR include Power Supply for Pentium II and AMD-K6 Microprocessors, High Power 5V to 3.xV Regulators, Local Regulation for Dual Voltage Logic Boards, Low Voltage, High Current Battery Regulation.
