Product Overview

The LTC1430CS#PBF is a high power high efficiency Switching Regulator Controller optimized for 5V to 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. It uses a synchronous switching architecture with two N-channel output devices, eliminating the need for a high power, high cost P-channel device. Additionally, it senses output current across the drain-source resistance of the upper N-channel FET, providing an adjustable current limit without an external low value sense resistor. The LTC1430 includes a fixed frequency PWM oscillator for low output ripple under virtually all operating conditions. The 200kHz free-running clock frequency can be externally adjusted from 100 to above 500kHz. It features low 350µA quiescent current, allowing greater than 90% efficiency operation in converter designs from 1A to greater than 50A output current.
  • All N-channel external MOSFETs
